数字信号的传输:1、实现滚降系数分别为0,0.5,1时信号时域频域和功率谱密度以及眼图的波形,并比较异同。
2、对(2/4/8)PSK,DPSK通信系统进行蒙特卡罗仿真,通过功率谱密度、误比特率来比较他们的性能(采用最佳接收方式)。
(Digital signal transmission: 1, to achieve roll-off coefficients were 0,0.5,1 time domain when the signal frequency and power spectral density, as well as eye-diagram of the waveform, and compare the similarities and differences. 2, (2/4/8) PSK, DPSK communication system, Monte Carlo simulation, through the power spectral density, bit error rate to compare their performance (to adopt the best way to receive).)

QPSK
提出了一个采用(2,1,7)卷积码+QPSK的中频调制解调方案,并在Xilinx公司的100万
门FPGA芯片上实现了该系统。该系统在信噪比SNR为6dB左右时可实现速率超过1Mbit/s、误码率
小于10-5的数据传输。
(Proposed a use of (2,1,7) convolutional code+ QPSK modulation and demodulation of the IF program, and in Xilinx' s FPGA chip one million on implementation of the system. The system SNR to 6dB signal to noise ratio at about the rate may achieve more than 1Mbit/s, less than 10-5 bit error rate of data transmission.)
