Abstract

Multithreshold decoders (MTD) for self-orthogonal codes (SOC) are discussed. It´s known MTD can provide near optimum decoding with linear complexity only. Bit-error rate performance of MTD in multipath Rayleigh and Rician fading channels is analyzed. Several questions of application of MTD with orthogonal frequency division multiplexing and multiple-input and multiple output technology for improving reliability of communication with unmanned vehicles are discussed. The performance of multithreshold decoders in such conditions is presented. Comparison with decoders for DVB-S2 low-density parity-check codes is presented. It´s shown MTD provides comparable with LDPC decoders performance at much lower complexity.
