系统的性能由比特错误率(BER)来衡量。
通过分析比特错误率和对比性能讨论了光学滤波带宽对接收信号质量的影响。
The effects of optical filter bandwidth on the received signal quality are discussed by analyzing bit error rate (BER) and contrast ratio performances.
实验结果表明，软判决检测的比特错误率普遍低于硬判决检测的比特错误率，在高斯噪声情况下，甚至能低0.169。
Experimental results indicate that the Bit Error Rate (BER) of soft-decision detection femains lower than that of hard-decision detection, even 0.169 lower in gaussian noises.
