Abstract :
We have analyzed the error performance of 16 QAM with optimum code mapping (OCM) and optimum threshold detection (OTD) in a Rician fading channel with and without the selective combining (SC) diversity technique. The error performance of OCM with OTD is compared to that of conventional code mapping (CCM) in a Rician fading channel. With the result of the analysis, it is found that the proposed OCM with OTD is superior to CCM with CTD. The adoption of a diversity technique with the proposed OCM with OTD can be considered as a good countermeasure for the Rician fading under a personal communication system (PCS) environment
