func_res5.m

基于OFDM的无线宽带系统仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator.

% this function will analyse results from non-adapted systems to 
% find the threshold,throughput for a certain target, given
% the discrete ber/fer/throughput vs SNR vectors
% this threshold will be put into the threshold tables and used later in
% adapted systems
