Analysis of characteristics of joint using of M-ary orthogonal stochastic broadband signals and LDPC codes

Information and Signal Processing

The article considers the question of increasing of noise-immunity of communication systems due to joint using of M-ary orhogonal stochastic broadband signals and low density parity check codes (LDPC codes). The substantiation of signal selection and method of coding is given, the analysis of noise-immunity is given and the efficient combination of coding and modulation parameters is defined.
