摘要：The iterative decoding in turbo code has very high decoding complexity. This paper adopts the improved Log-MAP algorithm for decoding of Space-Time Turbo Trellis Code (ST-Turbo TC) in the slow Rayleigh fading channels. Using the MacLaurin formulae, the proposed algorithm expands the logarithmic function of the Log-MAP. It makes the computation much easier and the operation of the hardware system much faster. Simulation results show that the proposed algorithm performs very closely to the Log-MAP algorithm for decoding of ST-Turbo TC in slow Rayleigh fading channels.
