Abstract :
This paper presents a class of complex orthogonal wavelet packets through optimization and proposes a complex wavelet packet based OFDM system (CWPOFDM). Besides, a serially implemented multistage MLSE/SIC (successive interference cancellation) detector is developed to retrieve the transmitted CWPOFDM symbols. By comparison, it is shown that the performance of CWPOFDM without cyclic prefix (CP) is close to or superior to that of DFT based OFDM (DFTOFDM) with CP, at the price of a little increased computational complexity
