수중 SIMO 채널에서의 블라인드 등화기 실험

Abstract

In this paper, we discussed for performance analysis of SOS based blind array receiver in underwater wireless communication. Since The underwater acoustic channel has shape of a wave guide, signal estimation in underwater wireless communication is suriously affected from multipaths of acoustic rays.. Training sequence is a solution to solve this problem, But the use of training sequence reduces the transmission throughput of signals. The paper used blind receiver to reduce this loss, and saw that the proposed receiver system enhanced the performance of blind receiver by using short matched filter. Simulations and anechoic water tank experiments verified that proposed system efficiently equalizes the original signal in underwater SIMO channel.
