Abstract

This paper proposes a novel orthogonal frequency division multiplexing( OFDM )transmission technique using all phase (AP) method and investigates the different effect of carrier frequency offset (CFO) on sub-carrier between AP method and original OFDM: the amplitude of inter-carrier interference (ICI) factors in AP method are the square of that in original OFDM, and there is no angle impact in AP method. Simulation results show AP method in OFDM improves the ability of anti-frequency-offset and quality of multimedia signal based on the new transmission is increased greatly.
