Erratum: A New Direct-Sequence Spread Spectrum Signal Detection Method for Underwater Acoustic Communications in Shallow-Water Channel (DOI: 10.21008/j.0860-6897.2021.1.06)

In the paper the author erroneously described in section 2, that both detection algorithms used in simulation and experimental tests (algorithm A and algorithm B) detect information that on the transmitting side has been transformed into the constellation symbols {-1, 1} in differential way. This only applies to algorithm B. Algorithm A, described in subsection …

A New Direct-Sequence Spread Spectrum Signal Detection Method for Underwater Acoustic Communications in Shallow-Water Channel

Direct-Sequence Spread Spectrum (DSSS) is one of the modulation and coding techniques used in Underwater Acoustic Communication (UAC) systems for reliable data transmision even at low signal levels. However, in a shallow water channel, there is a strong multipath propagation which causes a phase fluctuation of the received signal, affecting the performance of the spread-spectrum …
