我们研究并比较了星形 16 进制正交幅度调制 (Star-16QAM) 和方形 16QAM (Square-16QAM) 在概率整形 (PS) 和相干检测均匀方案中的性能。在PS技术的帮助下，与我们的数值模拟和实验中的统一方案相比，PS-Star-16QAM方案实现的误码率（BER）改善大于PS-Square-16QAM。因此，PS-Star-16QAM 在 BER 改善方面比 PS-Square-16QAM 显示出优越性。
We investigate and compare the performance of star-shaped 16-ary quadrature amplitude modulation (Star-16QAM) and square-shaped 16QAM (Square-16QAM) in the probabilistic shaping (PS) and uniform schemes with coherent detection. With the help of PS technology, the bit error ratio (BER) improvement achieved in the PS-Star-16QAM scheme is greater than that of the PS-Square-16QAM when compared with the uniform schemes in our numerical simulation and experiment. Therefore, the PS-Star-16QAM shows superiority over the PS-Square-16QAM in terms of the BER improvement.
