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.)

S60官方视屏播放器程序，可以装到手机上运行，但是在模拟器上运行会出问题。据说是因为视屏播放服务器的内核有问题，不能在模拟器上用。本人手机上测试成功。(S60 official video player program can be installed to run on mobile phones, but will run in the simulator problems. It is said that is because the screen play of the core server has problems, should not use the simulator. I test the success of mobile phones.)
