我们对基于低分辨率数模转换器的收发器中的概率星座整形增益进行了数值研究,该收发器利用了数字分辨率增强。对于优化的概率整形因子,可以实现 0.75dB 的信噪比增益。
We present a numerical study of probabilistic constellation shaping gains in low resolution digital to analogue converters based transceivers, which utilise digital resolution enhancement. A signal to noise ratio gain of 0.75dB for optimized probabilistic shaping factors is achievable.
