A Weighted Multi-band Algorithm Using Estimation BER in Underwater Acoustic Communication

The multi-band UWAS communication techniques are effective in terms of performance and throughput efficiency. However, the multi-band configuration in a particular band affects the output from the entire bands. This problem can be solved through a receiving end that analyzes error rates of each band. In this paper, we proposed an estimation BER algorithm which get the reliability of received data to set the weighting value to each band. Therefore, we analyzed the efficiency of multi-band transmission scheme with estimation BER and 3 [dB] performance gain is obtained.
