Abstract: For example, a STA may determine a pre-FEC padding factor value for a PPDU, the pre-FEC padding factor value in a range between 1 and 2Na, wherein Na is an integer greater than 2; set Na bits in a Signal (SIG) field of the PPDU to indicate the pre-FEC padding factor value; and encode a data field of the PPDU according to a FEC coding based on the pre-FEC padding factor value. For example, a STA may encode a data field of a PPDU according to a FEC coding based on a pre-FEC padding factor value and based on a condition that no post-FEC padding is to be applied for the PPDU; and set an LDPC extra symbol subfield in a SIG field of the PPDU to indicate whether or not an LDPC extra symbol is present based on encoding of the data field of the PPDU.

Abstract: An optical communication method and system with high spectral efficiency and low power consumption based on joint channel coding modulation relates to the technical field of high-speed fiber communication. The method includes a data acquisition step, a symbol multiplexing joint channel coding modulation step, a signal optical communication step, a channel equalization step, and a symbol demultiplexing step. The optical communication method and system improves the problems of relative independence of forward error correction channel coding (FEC) and high order modulation function modules, long code length dependence of FEC, limited spectral efficiency promotion under the limitation of fiber nonlinear effect, and high FEC decoding latency and power consumption in optical communication system. It is beneficial to improving the spectral efficiency and capacity of a coherent optical communication system and optimizing the system latency and power consumption.

Abstract: A decoding device includes a storage unit storing a first check matrix with a highest code rate that can be divided into blocks of P×P submatrices, the highest code rate being conceivable as a check matrix of a low-density parity-check code used in communication, where P is a positive integer; and a generation unit that generates, using a unit row of the first check matrix that includes submatrices in column directions, a first row where some blocks are replaced with zero matrices and at least one second row where specified blocks are replaced with zero matrices, with the other blocks of submatrices having 1s shifted by a specified fixed value, to generate a second check matrix with a lower code rate than the first check matrix.

Abstract: An example according to the present specification relates to a technique for configuring a preamble in a wireless LAN (WLAN) system. A transmitting STA may generate and transmit an EHT PPDU. The EHT PPDU may comprise an L-SIG field, an RL-SIG field, a first control field, and a second control field. A result of “modulo 3 operation” for a length field value of the L-SIG field may be set to “0.” The RL-SIG field may be configured to be the same as the L-SIG field. The first control field may comprise 3-bit information on the version of a PPDU, 6-bit information on a BSS color, and 7-bit information on TXOP.

Abstract: A method for transmitting a discrete fourier transform (DFT) DFT-S-OFDM signal including frequency domain reference symbols is disclosed. The method comprises: determining to null a plurality of data symbols prior to DFT-spreading; performing DFT-spreading including the determined null data symbols; puncturing an interleaved output of the DFT-spreading; inserting reference symbols in a frequency domain of the punctured and interleaved DFT-S-OFDM signal; and transmitting the DFT-S-OFDM signal with inserted reference symbols to a receiver. The transmitted DFT-S-OFDM signal enables the receiver to apply zeros corresponding to the reference symbols to an interleaved input of DFT-despreading, and cancel interference due to the puncturing by using all outputs of the DFT-despreading.
