| Abstract: | Aimed at the high complexity of the time domain and the conventional frequency domain equalization, the concept of modified frequency domain equalization algorithm is introduced to underwater acoustic (UWA) code division multiple access (CDMA) to simplify the calculation and to reduce the registers based on the distinction of UWA channels which contributes to the facilitation of hardware. It has been evaluated that the complexity of calculation and registers between conventional, simple and modified frequency domain equalization algorithm. Furthermore, the performance of the proposed method is testified in a lake experiment. |
