Abstract :
The traditional decision feedback equalizer embedded digital phase-locked loop (DPLL) only equalize single-channel received signal, in order to improve the performance of underwater acoustic communication, a spatial-equalization algorithm embedded DPLL is researched in this paper. Such algorithm proposed in this paper combines time gain from equalization process and space gain from spatial diversity process and track phase changes of communication channel. Simulation and trail results show the effectiveness of it.
