Suppression of optical beat interference-noise in orthogonal frequency division multiple access-passive optical network link using self-homodyne balanced detection
We propose a new technique which can reduce an OBI-noise in OFDMA link. It uses self-homodyne balanced detection in order to suppress the OBI-noise. The OSNR for BER of 10?5 is reduced by 2dB in the balanced detection compared with a single channel.
