Abstract
In this paper, an effective preamble structure with only one zero-value guard symbols for OFDM/OQAM systems is proposed to improve spectrum efficiency. Moreover, a preamble interference cancellation (PIC) based channel estimation (CE) scheme is proposed to mitigate the residual ISI in OFDM/OQAM systems. Simulation results prove that the proposed preamble with PIC based channel estimation is an effective structure for OFDM/OQAM systems.
