Channel Estimation Using Pilot Method for Underwater Filter Bank Multicarrier System

Filter bank multicarrier (FBMC) modulation is well-thought-out as a promising contender for communication systems, it may perhaps substitute orthogonal frequency division multiplexing (OFDM) in terrestrial communication and in underwater acoustic communication (UAC). Herein this paper, we insinuate the channel estimation by means of coding pilot and auxiliary pilot technique for underwater FBMC system. We contemplated multipath underwater acoustic channel with additive white Gaussian noise. Herein we equated the BER performance between OFDM and FBMC, the experimental outcomes ascertained that the BER of FBMC is better than OFDM exploiting multipath underwater acoustic channel.
