A wideband receiver system comprises a wideband analog-to-digital converter (ADC) module and a digital frontend (DFE) module. The wideband ADC is configured to concurrently digitize a band of frequencies comprising a plurality of desired channels and a plurality of undesired channels. The DFE module is coupled to the digital in-phase and quadrature signals. The DFE module is configured to select the plurality of desired channels from the digitized band of frequencies, and generate an intermediate frequency (IF) signal comprising the selected plurality of desired channels and having a bandwidth that is less than a bandwidth of the band of frequencies, where the generation comprises frequency shifting of the selected plurality of desired channels. The IF signal may be a digital signal and the DFE is configured to output the IF signal via a serial or parallel interface.

Methods and systems for ripple suppression in multi-phase buck converters may comprise a buck converter for providing an output voltage with controlled ripple current. The buck converter may include one or more main buck converter stages and one or more suppression buck converter stages coupled with the one or more main buck converter stages. The one or more suppression buck converter stages may provide suppression currents to reduce ripple currents generated in the one or main buck converter stages.

Methods and systems are provided for using frequency spreading during communications, in particular communications in which multiple carriers (or subcarriers) are used. The frequency spreading may comprise generating a plurality of spreading data vectors based on transmit data, such as by application of a spreading matrix to portions of the transmit data. Each spreading data vector may comprise a plurality of elements, for assignment to the multiple subcarriers. The receive-side device may then apply frequency de-spreading, to obtain the original transmit data. The frequency de-spreading may comprise use of the same spreading matrix on data extracted from received signals, which (the data) may correspond to the plurality of spreading data vectors.

A microwave backhaul transceiver comprises a plurality of antenna arrays, positioning circuitry, and signal processing circuitry. The microwave backhaul transceiver may determine, via the positioning circuitry, a location of the small cell backhaul transceiver. The microwave backhaul transceiver may, generate, via the signal processing circuitry, a beacon signal that uniquely indicates the location. The microwave backhaul transceiver may transmit the beacon signal via at least one of the antenna arrays. The beacon signal may be generated using a spreading code generated from a unique identifier of the location. The unique identifier of the location may comprise global positioning system coordinates and/or a street address. During the transmitting, a directionality at which the beacon radiates from a particular one of the antenna arrays may be varied such that the beacon is transmitted in multiple directions from the particular one of the antenna arrays.

A radar system comprises a transmitter and a receiver. The radar system is operable to define a near range and a far range. The radar system is operable to, during each one of a plurality of time intervals, repeatedly transmit, via the transmitter, a plurality of OFDM symbols. The transmitter is operable to select a transmit power for the transmission during the one of the time intervals based on from which of the near range and the far range reflections of the OFDM symbols are to be received during the one of the time intervals. The receiver is operable to receive reflections of the OFDM symbols, and process, in the receiver, the reflections of the OFDM symbols to detect objects within the near range and the far range.
