Abstract :
In this paper, we extend the iterative demapping technique to Observation Separation (OS), which is an iterative channel estimation and symbol detection procedure. We consider a BICM-ID on a multipath channel with coded packet oriented transmission system with 16-QAM. We propose here to analyse the influence of mapping in a turbo equalization. Then we proposed an optimized binary mapping of 16-QAM constellation in order to increase coding gain which can be used for some practically important cases.
