摘要

在随机序列和相干接收条件下，研究了芯片波形整形对DS-CDMA通信系统功率效率和频谱占用的影响。导出了在给定带宽占用下使多址干扰的平均功率最小的最佳芯片波形设计方法。通过与使用传统芯片整形脉冲的调制方案(如OQPSK和MSK)的一些已知例子的SIR增益和容量增加进行比较，说明了优化设计的芯片波形的性能改进。

DS-CDMA chip waveform design for optimal power-bandwidth performance

The effect of chip waveform shaping on the power efficiency and spectral occupancy of DS-CDMA communication systems is investigated assuming random sequences and coherent reception. A method for designing optimum chip waveforms that minimise the average power of the multiple access interference at a given bandwidth occupancy is derived. The performance improvements of the optimally designed chip waveforms are illustrated by comparing the achieved SIR gain and capacity increase with the figures of some known examples of modulation schemes (such as OQPSK and MSK) that employ conventional chip shaping pulses.
