Abstract
This paper derives minimum non coherent distances of block-coded TAPSK (twisted amplitude and phase shift keying) and 16QAM (quadrature-amplitude modulation), both using linear component codes. According to the derived distances, non coherent block-coded TAPSK (NBC-TAPSK) and non coherent block-coded 16QAM (NBC-16QAM) are proposed. If the block length is very small, NBC-16TAPSK performs best among all non coherent schemes and NBC-16QAM performs worse due to its small minimum non coherent distance. However, if the block is not short, NBC-16QAM has the best error performance because the code words with small non coherent distances are rare. Here it also changes the value of r and see the performance of BER and also see the effect of Rayleigh channel on BER.
