Description

In this document, the problem of OFDMA multi-user resource allocation based on MMSE channel
estimation is considered. Maximization of system capacity, based on available error-free instantaneous
estimated channel state information at the transmitter, is the goal. Optimal power distribution between
different subchannels is computed analytically, and it is shown that equal power allocation among
subcarriers is almost near the optimum capacity. Furthermore, the optimum number of pilots and the
amount of power allocated between pilot and data subcarriers is computed analytically. Moreover, it is
shown, trough simulation, that numerical results absolutely coincides the analytical computations.

MATLAB release MATLAB 7.11 (R2010b)
Other requirements This is a truly good job which is done in MATLAB. I hope people who read and use these codes enjoy it.
