Optimization of the Cascade Code Parameters by the Criterion of the Boundary Value of the Interference Band and the Selection of the Decoding Algorithm

Abstract

A coherent data transmission channel with pseudo-random tuning of the operating frequency (FH) is considered, a concatenated code based on an ensemble of orthogonal signals and a Reed-Solomon code, with various reception-decoding algorithms under conditions of simultaneous action on the channel of two interference – a barrage and a FH concentrated in a part of the band. The estimates of the boundary value of the part of the FH band covered by the interference, the characteristics of the optimal concatenated code, are obtained, and also the receive-decoding algorithm is selected, in which the boundary value of the part of the band covered by the interference takes the maximum value in a given interference environment
