In this paper, we receive BER curves for stochastic M-ary orthogonal signals with LDPC-coding scheme. This curves we use to modify physical level of OPNET Modeler software to estimate claster mesh-network noise immunity in presence of barrage jamming signal. Also shown influence of signal sets volume, signal spread factor, signal-to-noise ration on PER.
