编程产生一组随机的0、1二进制比特序列,分别用2ASK, 2FSK, 2PSK和2DPSK四种调制方式把它们调制到一个较高的载频上,调制参数自定,请给出前8个比特所对应的时域波形。
画出上述四种信号通过高斯白噪声信道后的相干解调器和非相干解调器的原理框图,并给出判决前的观测值的数学表达式。注: 如果某些调制方式无法进行非相干解调,请给出原因。
根据题2中的观测值的数学表达式,分别编程实现判决过程,将判决结果与原数据作比较,统计出各自在不同比特信噪比 值下的误比特率 ,然后画出 与 (dB)的曲线。建议 的范围为 0dB 到10dB, 以1dB为间隔。
将上述仿真得到的误比特率曲线与各自的理论值画在同一张图上进行比较并讨论。同时, 比较和讨论不同调制与解调方式的差错性能区别。(emulate 2ASK, 2FSK, 2PSK and 2DPSK using matlab)
