Tutor description

Several modulation techniques are defined in digital modulation, Here we are discussing about in four modulation techniques,8-PSK,8-TAPSK,16TAPSK and 16-QAM. In the paper we derive minimum non coherent distance(dnc)of block coded TAPSK and compare it with different modulation techniques, i.e. 8-PSK and 16-QAM using linear component codes.

In the paper we derive minimum non coherent distance(dnc)of block coded TAPSK and compare it with different modulation techniques, i.e. 8-PSK and 16-QAM using linear component codes. If the block length N is very small.NBC-16-TAPSK performs best among all non-coherent scheme and NBC-16QAM perform wrose due to its small minimum noncoherent distance. However, if the block length N is not short, NBC-16QAM has the best error performance because the code words with small non-coherent distances are rare. GENERAL TERMS-Non-coherent detection, block coded modulation(BCM), multilevel coding(MLC), bit error rate(BER), Signal to noise ratio(SNR). KEYWORDS-AWGN, Rayleigh, Flat fading channel related to SNR, that is high BER causes low SNR. High BER causes increases packet loss, increase in delay and decreases throughputin wireless channels, several models have been proposed and investigated to calculate SNR. All the models are a function of the distance between the sender and the receiver, the path loss exponent and the channel gain.The AWGN channel which introduces an unknown carrier phase rotation ha
