| Abstract: | Based on the main idea of iterative decoding. The principle of joint demodulation and the method of decoding are studied. And based on the study the paper puts forward the method of (realizing) the technique of joint iterative demodulation and decoding, the structure of the receiver, and the method of MAP demodulation. The result of experiements and application shows that using joint iterative demodulation and decoding can improve the performance of whole system. |
