Abstract: Underwater acoustic channel has the characteristics of severe multipath, rapid variation and estimation of its phase is difficult task. Hence achieving high data rate and reliable communication is a challenge for Underwater Acoustic Channel (UAC). Orthogonal frequency division multiplexing (OFDM) has emerged as a promising modulation scheme for underwater acoustic (UWA) communication. Inter symbol interference (ISI) can be avoided by transmitting a number of narrowband subcarriers by using a guard time. This paper deals with the evaluation of Bit Error Rate (BER) of Orthogonal Frequency Division Multiplexing (OFDM) system under different combinations of modulation techniques with convolution channel coding at different coding rates
