Abstract

This paper focuses on a multiple input multiple output (MIMO) orthogonal frequency division multiple (OFDM) system, which uses space frequency block coding (SFBC) and an intercarrier interference (ICI) estimation/mitigation module for high mobility environment. The proposed algorithm is with low complexity which is proportional to O(N) (instead of O(N³)) and flexibly to apply to single input single output (SISO)/MIMO systems. Simulation results affirm the theoretical analysis with an average of 3 dB gain improvement.
