Abstract:	A heterodyne envelope (HE) receiver (RX) is investigated in the context of orthogonal frequency division multiplexing (OFDM) passive optical networks (PONs). Impacts of limited roll-off factor of shaping filter and required guard-band (GB) are studied through numerical simulations, showing that the Carrier to Signal Power Ratio (CSPR) value plays a significant role in the systems performance. For a QPSK system with 10 Gbps bitrate and for a bit error ratio (BER) quality threshold of 10-3 we show an improvement of 10.8 dB in sensitivity and 25% in spectral efficiency by using an optimum CSPR value as compared to unity CSPR.
