Abstract

Compared to conventional cyclic prefix orthogonal frequency division multiplexing (CP-OFDM), polynomial cancellation coded (PCC-OFDM) systems have been shown to demonstrate robustness against carrier frequency offset (CFO), multipath delay and Doppler spreads. In this paper, we describe the hardware implementation of PCC-OFDM system on an FPGA based software defined radio platform to examine the error performance on a real wireless channel using National Instruments's universal software radio peripheral (NI-USRP) hardware. In our implementation, we examine the impact of real wireless channel in conjunction with impairments such as multipath distortion, CFO and noise on the received signals. A simple receive signal processing algorithm for carrier synchronization and equalization is used for both CP-OFDM and PCC-OFDM systems. For the cases considered, PCC-OFDM outperforms conventional CP-OFDM under the influence of multipath, CFO and noise.
