中文摘要	In this study,a class of Generalized Low-Density Parity-Check(GLDPC) codes is designed for data transmission over a Partial-Band Jamming(PBJ) environment. The GLDPC codes are constructed by replacing parity-check code constraints with those of nonsystematic Bose-Chaudhuri-Hocquenghem(BCH),referred to as Low-Density Parity-Check(LDPC)-BCH codes. The rate of an LDPC-BCH code is adjusted by selecting the transmission length of the nonsystematic BCH code,and a low-complexity decoding algorithm based on messagepassing is presented that employs A Posteriori Probability(APP) fast BCH transform for decoding the BCH check nodes at each decoding iteration. Simulation results show that the LDPC-BCH codes with a code rate of 1/8.5have a bit error rate performance of 1 10 6at signal-noise-ratios of 6.97 dB,4.63 dB,and 2.48 dB when the fractions of the band jammed are 30%,50%,and 70%,respectively.; In this study,a class of Generalized Low-Density Parity-Check(GLDPC) codes is designed for data transmission over a Partial-Band Jamming(PBJ) environment.
