| 摘 要： | 本文基于泛函分析中内积空间理论建立了信号空间，将时频信号表示成相互正交的矢量，然后对时频组合调制系统进行了性能分析。给出了在ＡＷＧＮ信道匹配子空间解调器的条件下，对四时四频系统进行性能分析的过程，分析的结果得到了计算机模拟试验的验证。文中最后也推广给出Ｍ进制ｎ时ｎ频时频组合调制的误码率公式。

| Abstract: | In this paper, the performance of time-frequency combined modulation systems is analyzed by use of inner product space theory combined with statistical theory. The key step of the analysis process is to represent time-frequency modulation signals as perpendicular vectors each other. The analysis process for time-frequency modulation signals transmitted over the additive white Gaussian noise (AWGN) channel is given. And the computer simulation results for the time-frequency modulation systems are also given. The computer simulation results show that the theoretical results are correct. |
