Abstract : | In this thesis, the dual-mode burst-error-correcting decoding algorithm is adapted to the multiple trellis-coded π/4 shift QPSK in order to achieve the improvement of bit error rate (BER) performance over fading channels. Rayleigh fading channels and Rician fading channels having the Rician parameter K = 5 dB are used in computer simulation, and the simulation results are compared with those of interleaving techniques. It is shown that under the constraint of the fixed overall memory quantity, the dual-mode adaptive decoding scheme gains an advantage in the BER performance with respect to interleaving strategies. |
