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

OFDM resource allocation for (single user) using greedy algorithm. the function of greedy algo. is written in C. so, one need to set up a compiler in matlab.
