Abstract :
The authors uses binary PSK signaling an additive white Gaussian noise channel and several code parameter choices in a computer simulation to illustrate the improvement in throughput efficiency when soft-decision decoding is used in the generalized hybrid ARQ (GH-ARQ) method. From the computational complexity standpoint, the use of GH-ARQ soft-decision decoding is indeed feasible, since the code lengths used are relatively short. Simulation results are compared with results for soft-decision scheme of G. Bennelli (1986)
