McDonald, " Point-to-point underwater acoustic communications using spread-spectrum passive phase conjugation., " J. Acoust. Soc. Am. 120, 247-257 (2006), who applied the DPSK method to high SNR data. For high SNR cases, the method works like a coherent Rake receiver, the performance of which has been extensively investigated in the literature. The performance issues are significantly different for low SNR data as discussed in this article.
