摘要

给出了M/sup / power载波跟踪环路损耗的一般表达式。该表达式应用于评估costas环型方案在二进制PSK(相移键控)和正交PSK系统中的性能，其中发射脉冲具有平方根提升余弦频谱，并且在接收机中使用匹配滤波器。数值结果表明，该系统对脉冲滚降因子的变化非常敏感。

Carrier recovery performance in PSK systems using transmission pulses with a square root raised cosine spectrum

A general expression is presented for the M/sup th/ power carrier tracking loop loss. This expression is applied to assess the performance of Costas-loop type schemes in binary PSK (phase shift keying) and quadrature PSK systems, in which transmission pulses have a square-root raised-cosine spectrum and matched filters are used in the receiver. Numerical results illustrate performance sensitivity to variations of the pulse roll-off factor.<>
