Abstract
The bidirectional equalization is an effective method for demodulating communication signals with weak strength since it improves the signal-to-noise ratio by obtaining additional diversity as well as temporal and spatial diversity when used in combination with the time reversal technique. In this paper, we will demodulate the communication signals acquired from biomimetic long-range acoustic communication experiment 2018 (BLAC18) conducted in East Sea of Korea in October 2018 using time reversal and bidirectional equalization techniques. It is shown that the bidirectional equalization including decision direct equalizer has the best error performance.
