8psk
(1) 分析QPSK调制、解调原理,并画出其系统框图;
(2) 产生等概率且相互独立的二进制序列,作为待传输的信号,并画出其波形;
(3) 进行8PSK调制,分别画出I、Q两支路信号经过乘法器后的波形以及8PSK调制波形;
(4) 产生均值为0,方差为1的加性高斯随机噪声,画出其时域波形及频谱;
(5) 将加性高斯随机噪声作为传输信道的干扰,画出接收端信号的时域图;
(6) 进行8PSK解调,输出解码序列,画出解调后信号波形;
(7) 计算系统信噪比、传输误码率。((1) analysis of QPSK modulation, demodulation, and draw the system block diagram (2) have equal probability and independent binary sequence as a signal to be transmitted, and draw the waveform and (3) 8PSK modulation, Draw the I, Q two way signal multiplier waveform and 8PSK modulation waveform (4) to produce zero mean and variance of an additive Gaussian random noise, to draw the time-domain waveform and spectrum ( 5) the additive Gaussian random noise interference as a transmission channel, to draw the time-domain diagram of the receiver signal (6) 8PSK demodulator output decoding sequence, draw the demodulation of the signal waveform computing system (7) signal-to-noise ratio, the transmission bit error rate.)
