Concatenated Channel Decoding with space time block codes and differential M-PSK Modulation

초록

Abstract - Space time block codes provide an effective way to fully exploit both transmit diversity and receive diver- sity to combat the impairments of wireless fading channel. To achieve a significant coding gain space time block codes have to be concatenated with outer code. In this paper, we propose a transmission system with space time block coded differential M-PSK modulation concatenated with channel co- des. We describe the proposed system which in fact is a " serial turbo code", and explain how to implement the itera- tive decoding in our system by use of SISO module. The simulated results show that the significant coding gain is achieved in the proposed system.
