Abstract
This paper proposes a hybrid shortened transmission/expanding reception technique and single carrier modulation with a zero forcing frequency domain equalizer when a single carrier modulation with a guard period is transmitted. Regarding single carrier transmission data as shortened OFDM transmission data allows an expanding reception technique and a maximum ratio to be combined in the receiver, and a parallel single carrier modulation with a frequency domain equalizer is used as a secondary receiver. The proposed hybrid scheme does not have channel codec but simulation results show it has better performances in comparison with the coded OFDM algorithm at the expense of algebraic calculations and FFT executions.
