摘要

Methods and devices are disclosed for encoding source words and decoding codewords with LDPC matrices. The Methods and devices use a LDPC matrix Hn of lifting factor Z. The LDPC matrix Hn comprises a plurality of submatrices, each submatrix having a size of Z×Z, and at least one submatrix has m1 diagonals of “1” m1 is an integer>=2.

說明書

The processing system 150 may include one or more processing devices 152, such as a processor, a microprocessor, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a dedicated logic circuitry, or combinations thereof. The processing system 150 may also include one or more input/output (I/O) interfaces 154, which may enable interfacing with one or more appropriate input devices and/or output devices (not shown). One or more of the input devices and/or output devices may be included as a component of the processing system 150 or may be external to the processing system 150. The processing system 150 may include one or more network interfaces 158 for wired or wireless communication with a network, such as but not limited to, an intranet, the Internet, a P2P network, a WAN, LAN, a WLAN and/or a cellular or mobile communications network such as a 5G, 4G, LTE or other network as noted above. The network interface(s) 208 may include wired links (e.g., Ethernet cable) and/or wireless links (e.g., one or more radio frequency links) for intra-network and/or inter-network communications. The network interface(s) 158 may provide wireless communication via one or more transmitters or transmitting antennas, one or more receivers or receiving antennas, and various signal processing hardware and software, for example. In this example, a single antenna 160 is shown, which may serve as both transmitting and receiving antenna. However, in other examples there may be separate antennas for transmitting and receiving. The network interface(s) 158 may be configured for sending and receiving data to the backhaul network 110 or to other user devices, access points, reception points, transmission points, network nodes, gateways or relays (not shown) in the network 100.
