A PVT calculation device includes a memory; and one or more processors in communication with the memory configured to perform operations including: receiving observations and ephemerides from satellites to obtain PVT data of the satellites and predicted PVT results of the receiver; setting up observation functions respectively corresponding to the satellites; calculating by a least square solution first estimated PVT results of the receiver based on the observation functions; iteratively eliminating by a Random-Sampling Iterative Kalman Filter (RSIKF) algorithm fault observation functions from the observation functions in an inner cluster until no fault observation functions detected in the inner cluster; calculating by the RSIKF algorithm a second estimated PVT results of the receiver using the observation functions in the inner cluster; and outputting final estimated PVT results of the receiver. The PVT calculation device may calculate the PVT results of the receiver with improved accuracy and stability.

A Weil code generator and a method of generating Weil codes with a Weil code length (N) are provided. The Weil code generator includes a plurality of parallel channels (), a multi-channel read arbiter (), and two parallel Legendre ROMs (), which are connected in series. A channel of the plurality of channels stores a current Weil code to demodulate signals from a satellite. The multi-channel read arbiter () may determine a win channel from the plurality of channels. The two Legendre ROMs () respectively store a first and a second Legendre sequences (LS1, LS2) each having a Legendre sequence length (2N) being double the Weil code length (N). The Weil code generator may generate Weil codes efficiently.

Embodiments of the present disclosure provide a resource allocation method, a packet communication method, and an apparatus. The resource allocation method includes: dividing, by a controller, a cloud data center network into multiple independent logical zones; allocating a corresponding tunnel label range to each logical zone; when a virtual network request for allocating a resource to a tenant is received, searching the logical zones to obtain a logical zone that meets the virtual network request; and allocating a tunnel label to the tenant according to a tunnel label range corresponding to the logical zone that meets the virtual network request. Because each logical zone is independent, during tunnel label range allocation, a same tunnel label range can be allocated to different logical zones. In this way, a same tunnel label can be allocated to different switches in different logical zones, implementing reuse of the tunnel label.

An integrated pylon structure for a propulsion system is suitable for one end to be connected to an aircraft wing and the other end to be connected to an aircraft engine. The pylon structure includes a pylon box section () formed from an upper and a lower bean, a frame () and a side wall panel. The pylon structure has a thrust reverser hood connection structure, provided on the side wall and connected with a nacelle thrust reverser hood having a front fixed hood () and a rear movable hood (). A guide rail allows the rear movable hood to slide and open relative to the pylon box section. The engine thrust reverser hood is directly connected to the side wall of the pylon box section and a guide rail on the side wall guides the opening of the thrust reverser hood.

A treatment process of persistent organic pollutants contained in particles is provided. Said process includes reacting persistent organic pollutant in particles under hydrothermal conditions in the presence of Feand Fe. Several beneficial effects can be achieved, including 1) no other additive is needed during the reaction process; 2) Feand Feare safe, cheap and extensive sources; 3) because Feand Feare dissolved, they can fully disperse into particles, and fully contact can be achieved, thus obtaining a decomposition rate no less than 70% of the persistent organic pollutants is under subcritical conditions.

An apparatus to enable half-duplexing capabilities in a two-way communication device is disclosed. The apparatus estimates the signal power and background noise of a first input signal and a second input signal during approximately the same period. The apparatus further provides at least one control signal based on the result of one or more determinations. These determinations may include whether the estimated signal power of at least one of the first and second input signals exceeds a threshold value; whether the estimated signal power of the first input signal exceeds the sum of a first threshold value and the estimated background noise of the first input signal; and whether the estimated signal power of the second input signal exceeds the sum of a second threshold value and the estimated background noise of the second input signal. Other embodiments for use with two-way communication devices and related methods are also disclosed.

A method, system, and apparatus for squelching a signal in telecommunications systems. The apparatus includes a filter, two power detectors, a divider, two comparators, a logic gate, and a gain control block. The apparatus receives an input signal, and the power of the signal is detected. The input signal is also filtered to pass only the noise portion of the signal, and the power of the filtered signal is detected. A ratio between the filtered signal power and the input signal power is determined. A first comparator receives the filtered signal power and a second comparator receives the ratio of the filtered signal power and the input signal power. The logic gate receives the outputs from the first and second comparators. The gain control block receives as inputs the logic gate's output and the input signal to the apparatus. The gain control block may attenuate the input signal based on the logic gate's output. The gain control block generates the output signal of the apparatus.

A method and apparatus for demodulating an input signal in a selectable intermediate frequency system is disclosed. The apparatus includes a front end module, a filter, and a phase lock loop (PLL). The front end module mixes the input signal with an oscillating signal. The filter includes at least one characteristic that is selectable to configure an intermediate frequency. The PLL demodulates an output frequency based on the output of the filter.

A system and method are provided for calibrating for an I/Q mismatch of a direct conversion receiver based on a random signal having a two-dimensional I versus Q trajectory, such as radio frequency (RF) noise. In general, the random signal is received and downconverted to a quadrature baseband signal having an in-phase component and a quadrature component. The variance of the in-phase component, the variance of the quadrature component, and the covariance of the in-phase component with the quadrature component are computed based on samples of the quadrature baseband signal. A correction matrix used to compensate for the I/Q mismatch of the receiver and/or I/Q mismatch including a gain mismatch and a phase mismatch of the receiver is then computed based on the variance of the in-phase component, the variance of the quadrature component, and the covariance of the in-phase component with the quadrature component.
