摘要

为了提高光接入链路的传输容量，提出了非正交频率正交调幅(NOFQAM)。在64-NOFQAM的情况下，尽管比16-QAM多增加了2位/符号，但信道带宽没有增加，信噪比也没有降低。

Improvement of optical access M-QAM transmission capacity using DSP based non-orthogonal frequency shift keying

Non-orthogonal frequency quadrature amplitude modulation (NOFQAM) is proposed to improve the transmission capacity of optical access link. In case of 64-NOFQAM, both no increase of channel bandwidth and no reduction of SNR were observed despite the increase of two more bits/symbol compared with 16-QAM.
