| 摘 要： | 基于自纠错码的二级脉冲幅度调制与脉冲宽度调制(PWAM)光纤传输技术,对系统中的接收机灵敏度进行了分析.在模拟信号信噪比不小于50 dB,数字信号误码率不低于10－9情况下进行仿真.结果表明,在没有增加系统复杂性的前提下,使用自纠错码时二级脉冲幅度调制以及脉冲调制光纤接收机灵敏度将有1.1 dB的改善. |

| Abstract: | The performance of 2-level pulse amplitude modulation and analogue pulse width modulation(PWAM) system based on self-error-correction code was analyzed.The system performance was evaluated by considering the signal to noise ratio(SNR) of 50 dB for analogue signal transmission and bit error rate(BER) of 10-9 for digital signal transmission as a lower bound.Computer simulations show that the receiver sensitivity of PWAM system with self-error-correction code can get 1.1 dB improvement without complexity. |
| Keywords: | Optical communication Pulse width modulation Pulse amplitude modulation Repetition code |
