Analysis of pilot symbol assisted modulation using modified long range prediction algorithm for rayleigh fading channel

The need for spectrally efficient transmission on wireless channels can be achieved by adaptive transmission in which channel prediction is an important tool to combat the harmful effects of fading. The study in this paper has been emphasized to investigate the channel prediction technique using pilot symbol assisted modulation (PSAM). This technique is implemented using modified long range prediction (MLRP) and estimation of signal parameters using rotation invariance technique (ESPRIT) algorithm. This paper compares PSAM, with other techniques and also put some results for Wireless LANs. A significant improvement in terms of mean square error, predictor order, predicted channel envelope and bit error rate has been achieved.
