Filter-bank design for multicarrier modulation systems with MPSK based on symbol-error-rate evaluation

A closed-form symbol error rate (SER) formula for a generic OFDM system with M-ary phas shift keying (MPSK) modulation, and optimal phase detector for each subchannel, is derived. by employing the derived SER formula as the objective function, a novel OFDM system based on designed complex-valued unitary filter banks is presented to minimize the SER. A detection algorithm is presented for a generic OFDM system to jointly detect subchannel symbols received in one time frame. Monte-Carlo numerical simulations are performed to verify the theoretical SER analysis and compare the error performance of the proposed OFDM system with DFT-based OFDM and DWMT systems, and the new joint detection algorithm with the cinventional subchannel detection algorithm. The above efforts provide systematic approaches for the OFDM error performance analysis and the OFDM system design.

Based on the filter bank, the theory of multi-carrier modulation using Orthogonal Frequency Division Multiplexing (OFDM) and Modified Discrete Fourier Transform (MDFT) filter bank has been discussed and the detailed derivation process has been given. Following these discussions, the actual implementation of MDFT filter bank in multi-carrier modulation systems has been discussed, and then the comparison of their prototype functions, Peak to Average Power Ratio (PAPR) and Symbol Error Rate (SER) are drawn. Experimental results demonstrate that compared with the OFDM system, prototype functions of MDFT have obvious advantage in spectrum leakage. In terms of PAPR, they have similar performance. Whether using QPSK or 16QAM modulation, MDFT is superior to OFDM in symbol error rate as a whole and with increasing of filter length L, the advantage becomes more and more apparent.
