The present disclosure relates to a method, system, and non-transitory computer-readable storage medium for constructing a base matrix of a PBRL LDPC code, comprising: determining at least one candidate sub-matrix of a PBRL LDPC code based on a base matrix of a QR-QC-LDPC code; obtaining at least one count of cycles with at least one preset length for each of the at least one candidate sub-matrix; and determining a first sub-matrix of the base matrix of the PBRL LDPC code based on the at least one count of cycles.

Method, system, device and storage medium for constructing base matrix of PBRL LDPC code

A method for decoding a cyclic code is disclosed. The method includes: determining a plurality of syndromes for the cyclic code; determining, by a hardware processor, a first coefficient and a second coefficient based on the plurality of syndromes; determining, by the hardware processor, a third coefficient based on the second coefficient; and generating an error-locator polynomial based on the first coefficient, the second coefficient, and the third coefficient.

Methods, systems, and computer-readable media for decoding a cyclic code

A method for decoding a (n, k, d) cyclic code is disclosed. The method includes: receiving a word corresponding to the cyclic code; constructing a look-up table, wherein the look-up table includes k syndrome vectors and k error patterns; computing a syndrome vector of the received word by a hardware processor; comparing the weight of the syndrome vector of the received word with an error-correcting capacity; decoding the received word by adding the received word and the syndrome vector if the weight of the syndrome vector of the received word is not more than the error-correcting capacity; decoding the received word by inverting bits in the message section in sequence and re-compute a syndrome vector of the inverted received word if the weight of the syndrome vector of the received word is more than the error-correcting capacity.

Provided is a positioner for reinforcing steel bars of tunnel side wall. At least two groups of reinforcing steel bar positioning arm mechanisms are provided on the same side of an inverted trestle (). The reinforcing steel bar positioning arm mechanism comprises a large arm (), a medium arm () and a small arm (). The large arm () is driven by a first telescopic cylinder () to rotate around a hinge point, such that the large arm () implements rotation in the horizontal direction. The medium arm () is composed of three second telescopic cylinders () in a Z-shaped arrangement in the vertical plane, such that the small arm () implements rotation or expansion in the vertical plane. Two arm rods of the small arm () are each provided with a third telescopic cylinder () to implement the expansion of the arm rod.

Positioner and positioning method for reinforcing steel bars of tunnel side wall

The invention provide a control method, including: obtaining a time division scheme of a STA in a next cruise monitoring period, where the next cruise monitoring period includes N adjustment periods and N monitoring periods determined by means of division according to N preset points; configuring control information according to the time division scheme, where the control information is for controlling an operating status of the STA in each adjustment period in the next cruise monitoring period; and sending the control information to the STA.

Control method and apparatus, and network controller

Examples of the present disclosure provide a channel access period allocation method. The method includes: receiving, by an access point (AP), first information sent by a first station (STA) for requesting a dynamic service period (DSP) from the AP; and sending, by the AP, second information to the first STA to instruct the first STA to send a data frame to the AP in a first DSP, where a start time of the first DSP falls within a first preset time period following an end time of an SP of the first STA, and the first DSP requested by the first STA is pre-allocated to a second STA having a priority that is lower than that of the first STA, where a time delay of the first STA for sending the data frame to the AP satisfies a time delay requirement of a quality of service QoS in the first preset time period.
