说明：  对常见的调制信号在软件无线电的通用平台下进行调制解调。所有信号均通过正交分解后，在一个同用的平台上进行调制，然后通过各自的解调算法解调。(right common modulation radio signals in the software under a common platform for modulation and demodulation. All signals are orthogonal decomposition, the same one used on the platform for modulation and demodulation through their respective demodulation algorithm.)

数字频带通信系统 输入：首先输入模拟信号，给出此模拟信号的时域波形。 数字化：将模拟信号进行数字化，得到数字信号，可以选择PCM编码。 调制：可以选择简单的二进制数字调制方式。例如振幅键控(2ASK)、相移监控（2PSK）、频移键控（2FSK）、差分相移键控（DPSK）等。要求每个题目至少选择两种调制方式。有能力的同学也可以选择其它高效的调制方式?例如多进制数字振幅键控等?给出调制后信号的时域波形。 信道：假定信道属于加性高斯信道?或自行设计。 解调：相应的2ASK、2PSK、2FSK、DPSK解调，仿真获得解调输出波形。 PCM解码：给出解码后的模拟信号的时域波形，并与输入信号进行比较。 系统性能分析：比较在不同调制方式下，该数字频带传输系统的性能指标，即该系统的输出误码率随输入信噪比的变化曲线。(Digital frequency band communication system)
