| 摘 要： | 提出了一个在ＭＰＳＫ ＤＳ／ＣＤＭＡ接收机中进行载波跟踪的新方案．该方案用两个对称的Ｘ相关器形成一个鉴频器．理论分析表明,该方案的跟踪范围是符号速率的两倍,并且与ＭＰＳＫ的键控相位数及扩频码的码长无关．

| Abstract: | This paper presents a new method for carrier recovery in a direct sequence (DS) code division multi-access (CDMA) receiver. The data demodulation scheme used is multiple phase shift keying (MPSK). The proposed scheme employs two balanced X-correlators to form a frequency discriminator. Theoretical analysis indicates that the proposed method has a tracking range that doubles the symbol rate, and the tracking range is independent of the keying phase number of the MPSK modulation. |
