matlab仿真程序，产生QPSK调制的信号，严格按照QPSK的调制步骤分I路Q路产生信号，最后两路相加，产生已调信号，调制信号随机产生，载波信号是余弦信号。(matlab simulation program to produce the QPSK modulation signal, in strict accordance with the QPSK modulation of the sub-step road Q road I have a signal, the sum of the last two, have been transferred signal, randomly generated modulated signal, carrier signal is a cosine signal.)

比例导引弹道仿真，目标方向速度可变，非插值法，xy面投影，xz面投影均遵循比例导引，合成后构成三维图形。(Proportional navigation trajectory simulation, variable speed target direction, non-interpolation method, the xy plane projection, the xz surface projection are follow the proportional navigation guidance, synthetic After a three-dimensional graphics.)

二维图像的读取，辨认，分析，并且用神经网络进行，判定哪些图片可以归为一类(Two-dimensional image reading, identifying, analyzing, and using neural network to determine which pictures can be classified as a class)

【matlab编程代做】 语音为基础的生物识别系统 可以作为参考使用源码([Do] matlab programming generation voice-based biometric systems can use as a reference source)

由于硬判决在判决过程中将接收直接判决为[1 0],而损失了相应的近似信息，导致了接收信息在某种意义上的浪费。软判决将接收电平量化，尽可能保存相应的信息，故可以提高译码性能。(soft descision decoding)
