摘要

In this paper, we conduct the window design for single-input single-output (SISO) and multiple-input multiple- output (MIMO) OFDM systems. The key value of this paper is to optimize the receiver SINR when carrier frequency offset (CFO) and phase noise both affecting an OFDM system. To our best knowledge, this is the first research to design window coefficients through leveraging the CFO and phase noise statistics for SISO and MIMO OFDM systems over frequency-selective channels. CFO and phase noise will destroy the orthogonality of OFDM system and lead to inter-carrier interference (ICI). Simulation results show that our proposed method can improve the system performance.
