Frequency-Domain Diversity Combining Receiver for ACO-OFDM System


This paper proposes a replacement receiver based mostly on frequency-domain diversity combining (FDDC) for an asymmetrically clipped optical orthogonal frequency-division multiplexing (ACO-OFDM) system. Compared with its time-domain diversity combining (TDDC) counterpart, the FDDC receiver is capable of a lot of effectively exploiting the frequency selectivity of the channel to any improve the detection performance, which is proved by postcombining signal-to-noise-ratio (SNR) analysis. An enhanced version of the FDDC receiver, which is called eFDDC, is also proposed subsequently. It allows for optimal choice among multiple sets of candidate symbol vectors based mostly on signum matrix estimation. Simulation results show that the proposed FDDC and eFDDC receivers outperform the TDDC receiver. With a sufficient number of candidate image vector sets, the eFDDC receiver even outperforms a quite iterative receiver, which is known to possess superior performance in current literature, nonetheless the complexity of eFDDC is lower because of the avoidance of matrix inversion. Those facts suggest that the FDDC and eFDDC receivers are strong receiver candidates for the ACO-OFDM system.
