| 摘 要： | 对流层散射信道作为功率和带宽双重受限的信道,对信号形式的选择必须兼顾峰均功率比和带宽利用率2个方面。针对目前大容量散射通信系统中所采用的同频交叠升余弦 QPSK 和平方根升余弦 QPSK 两种信号形式,分别讨论了它们的时域和频域特性及其实现方式,并对其性能进行了分析比较。

| Abstract: | Both the PAR and bandwidth must be taken into consideration when selecting signal format in troposcatter communi- cation,because the troposcatter communication channel is both power-limited and bandwidth-limited.The characteristic in time do- main and frequency domain of stacked raise cosine format and square-root raise cosine format are introduced in this paper,and com- parison of them is also presented. |

| Keywords: | troposcatter communication square-root raise cosine stacked raise cosine partial response system |
