| 摘 要： | 在移动通信领域中,MC CDMA是一项非常有前景的高比特率、高容量传输技术.MC CDMA的一个缺点是峰值平均功率比(PAPR)高,这将会导致使用高功率放大器时的非线性失真及误码率性能的降低.多种降低PAPR的方案已提出.本文对各种方法进行分析比较,并将其中一些方法进行结合,产生新的方案,对今后这方面的研究也提出一些建议.

| Abstract: | MC-CDMA is a very promising technique for high-bit-rate and high capacity transmission in mobile communications. One disadvantage of MC-CDMA is the high Peak-to-Average Power Ratio (PAPR) that results in nonlinear distortion at a high power amplifier (HPA) and the degradation of the bit error rate (BER). Many methods for reducing PAPR have been proposed,and were analyzed and compared in this paper. A new method based on combining several methods and some suggestions about research in the future was also proposed. |
