中文摘要：

分析了PTS副信息在MC-CDMA系统中对传输性能的影响,提出了一种适用于MC-CDAM系统的新的PTS盲检测算法,该算法在接收端将解扩过程与PTS相位恢复相结合,根据部分解扩信号选取最优相位因子,在相位恢复的同时生成解扩信号。与传统算法相比,该算法不需要传输任何副信息,传输性能稳定,能有效提高MC-CDMA的频谱效率和鲁棒性。

英文摘要：

In this paper,a blind PTS scheme in MC-CDMA systems is proposed.Based on the relationship between the dispreading codes and side information,the new scheme utilizes the phase recovering with the partial dispread signal,and makes the optimal decision based on minimum power error of the dispread signals.Simulation shows that compared with the conventional PTS scheme,the proposed scheme can recover the phase information without SI at the receiver and provide better frequency efficiency and transmitting performance.
