Abstract

In this paper, we present a study of the combined use of pilot-assisted (PA) electrical PAPR reduction technique and O-OFDM utilising G light emitting diode (LED) groups. In comparison with basic O-OFDM with G = 16, simulation results show that PA technique is capable of reducing G to 3 in order to achieve the same PAPR of approximately 11 dB using P = 5 at complementary cumulative distribution function (CCDF) of 10-3. The PAPR reduction gain using PA technique is achieved with less hardware complexity, but at the expense of increased computational complexity at the transmitter without sacrificing the bit error rate (BER) performance of the system.
