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

特殊随机矩阵的生成，包含两个程序，一个可以随机生成行和和列和均为K的0-1矩阵，另一个可以随机生成稀疏矩阵。-Matrix generation,concluding two program,one can generate the 0-1 matrix that have the same row sum and column sum,the other can generate sparce matrix.

此程序写了，任意给定两个数，互相作为底数和指数，再求和。如果不满足条件，报错。-This program was made, any given two numbers to each other as the base and index, and then sum. If does not meet the conditions, an error.
