Abstract :
FFH-OFDM combines fast frequency hopping (FFH) with regular OFDM symbols and it shows better performance in time-varying multi-path fading environments. This paper considers the precoding matrix and its receiver algorithm, simulation results show the difference. An implementation method of precoding in field programmable gate array (FPGA) is also discussed.
