OFDM Based SER and MSE Analysis in Cooperative Underwater Acoustic Communication

Underwater communication is one of the unique and challenging fields in communication engineering in the case of both designing and communication. Previous papers explained about different views in acoustic based underwater communication. Communication with acoustic waves is suitable type of wireless transmission with sound waves underwater. This paper explains about SER and MSE analysis of AF relay based cooperative underwater communication based on CGM-MP-SAGE algorithm. Here in this paper it summarizes estimation and equalization with SAGE algorithm of acoustic waves through underwater. This is a review paper to analyze the error rate performance and reliability of UWAC with respect to the SNR for different signal parameters, mainly MP, perfect CSI and MP SAGE algorithms, Doppler rates, resolution factors, multipath with variable lengths and pilot spacing based on BPSK modulated OFDM signals.
