Performance of serially concatenated convolutional codes with binary modulation in AWGN and Noise Jamming over Rayleigh fading channels

摘要

In this dissertation the bit error rates for serially concatenated convolutional codes (SCCC) for both BPSK and DPSK modulation with different channel conditions and with (and without) spread spectrum are considered. For low signal-to-noise ratios simulation results are used while for higher signal- to-noise ratios an average upper bound is developed to illustrate the achievable performance of SCCC. The theoretical bounds for SCCC BPSK and SCCC DPSK with AWGN, noise jamming Rayleigh fading and spread spectrum are developed analyzed and compared with simulation results. The differences in performance between SCCC BPSK and SCCC DPSK are described. Implications for the military communications user and jammer are also discussed,
