摘要
A coherent optical heterodyne CPFSK receiver with limiter-discriminator (LD) detector, which cannot be degraded by quantum phase noise of lasers when the frequency deviation ratio h is equal to 1, will be proposed. The receiver can give the same bit error rate as the ideal digital DPSK system. In addition, 1/2 exp ( - SNR) can be considered as the upper bound of the minimum error rate of the CPFSK-LD detector.
