A Study of Practical FPGA Implementation of AE-OP-OFDM

AE-OP-OFDM (AutoEncoder-orthogonal precoding-orthogonal frequency division multiplexing) has been proposed to simultaneously suppress the high peak-to-average power ratio and the out-of-band emission of OFDM signals; however, its computational cost is high. This study considers a method to reduce the complexity of AE-OP-OFDM for practical field-programmable gate array (FPGA) implementation. The performance is verified using numerical and FPGA board experiments. The computation cost of AE-OP-OFDM is suppressed to 0.08% while maintaining its performance.
