论文摘要
在本文中，我们通过分析表征位决策区域和位置来分析表征$ M $ -ARY脉冲振幅调制（$ M $ -PAM）的封闭形式的比特率（BER）表达式（BER）表达式（$ M $ -PAM）。然后使用所获得的表达来得出矩形正交振幅调制（QAM）的条件BER，以给定相噪声的给定值。数值结果表明，相位噪声对条件BER性能的影响与星座大小成正比。此外，观察到，与其他矩形星座相比，鉴于星座的大小，平方QAM实现了最低的相位噪声诱导的性能损失。
In this paper, we newly present a closed-form bit-error rate (BER) expression for an $M$-ary pulse-amplitude modulation ($M$-PAM) over additive white Gaussian noise (AWGN) channels by analytically characterizing the bit decision regions and positions. The obtained expression is then used to derive the conditional BER of a rectangular quadrature amplitude modulation (QAM) for a given value of phase noise. Numerical results show that the impact of phase noise on the conditional BER performance is proportional to the constellation size. Moreover, it is observed that given a constellation size, the square QAM achieves the lowest phase noise-induced performance loss compared to other rectangular constellations.
