we study the resource allocation problem for the multiuser orthogonal frequency division multiplexing (OFDM)-based cognitive radio (CR) systems with proportional rate constraints.

说明：  数学建模算法及应用电子书PDf版本，数学建模入门必备(Mathematical Modeling Algorithms and Application of PDf Edition of Electronic Books)

用matlab 实现bpsk的误码率蒙特卡洛仿真，可以作为编程的范例来用(Using matlab to achieve bpsk BER Monte Carlo simulation ，could be used as a programming paradigm)

这个是霍夫曼编码的问题，要求输入只含有ABCD的四句话，且每句8个字符的长度，然后求出四个字符每个的概率，然后当成权值计算霍夫曼编码，我的这个程序已经实现了输入、概率统计、计算出霍夫曼编码存在了bian[]这个数组中(hoffuman decoding)

分别对64QAM和BPSK进行蒙特卡洛仿真，并绘出误码率曲线(BPSK and 64QAM are carried out, MonteCarlo simulation, respectively,and draw the curve of bit error rate)
