Abstract :
Spatial diversity equalization (SDE) using a vertical receive array and a joint space-time equalization criterion are applied to minimize intersymbol interference (ISI). An ocean acoustic model is used, and the parabolic wave equation is solved to find the acoustic channel impulse response. Mean square error and probability of symbol error are computed for a variety of system parameters and indicate the advantages of SDE
