压缩感知中导频插入信道估计算法的正交匹配跟踪，贪婪迭代，-Insert channel estimation orthogonal matching tracking algorithm greedy iterative compressed sensing pilot,

利用贪婪算法对ofdm系统进行子载波和功率分配，在误码率一定的情况下，是发射端的功率最低-Greedy algorithm using ofdm system subcarrier and power allocation, bit error rate in certain circumstances, is the minimum transmitter power

greedy algorithm in OFDM resource allocation (single user)

属于贪婪算法中正交匹配追踪算法，用于信道估计预编码中，利用稀疏性，减小信道估计和反馈的开销，此算法的输出为所需要的系数矩阵，压缩包中还有一些说明-Belonging greedy algorithm orthogonal matching pursuit algorithm, used for channel estimation pre-encoding, the use of sparsity, channel estimation and feedback to reduce the ov
