说明：  这是手机的射击游戏,有一定的参考价值,可编译(shooting games, a certain reference value, compiler)

移动通信系统的仿真 蜂窝小区系统中的切换(Switch in the honeycomb cell system of mobile communication systems simulation)

说明：  这是一个基于OPtisystem下的对于8PSK信号的仿真，可用于通信工程作业的一般仿真系统。(This is a simulation system of 8PSK signal based on OPtisystem, which can be used in general simulation system of communication engineering operation)

信号进入信道，经过高斯噪声的干扰，经过QPSK调制以后的时延 (The signal enters the channel, after the interference of the Gaussian noise after a delay after the QPSK modulation)

matlab实现的qpsk调制过程，很详细，包括调制解调、自动频率控制和误码率分析等过程(matlab implementation qpsk modulation process, very detailed, including the modulation and demodulation, automatic frequency control, and error rate analysis process )

turbo码的译码，以及包含LOGMAP和SOVA两种算法(turbo code decoding, and includes two algorithms LOGMAP and SOVA)

说明：  构建了基于压缩感知的信号处理系统，并用BPDN算法将频域稀疏信号恢复出来，BPDN算法与GPSR算法类似，属于基追踪算法，复杂度较高但较为精准。(A signal processing system based on compressed sensing is constructed, and bpdn algorithm is used to recover the sparse signal in frequency domain. Bpdn algorithm is similar to GPSR algorithm, which belongs to base pursuit algorithm, with higher complexity but more accurate.)

利用matlab实现ASK和FSK调制解调过程对比他们的不同(Using MATLAB to realize the modulation and demodulation process of ASK and FSK, their differences are compared.)
