摘要：
Orthogonal Frequency Division Multiplexing (OFDM) is a method that can combat multi-paths, fully use the frequency band, has high data rate and has a promising future in UWA communication. While longer the transmission range, worse the underwater conditions with multi-paths and Doppler offset, which needs to design the system parameters and take practical methods to improve the system. In this paper, a new PRP-OFDM (A Pseudo random Postfix OFDM) algorithm is proposed, which has a good performance and low-complexity.
