average3.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.

% mean of the dB value
% dB --> linear --> mean --> dB
function y = average3(x,average_factor)
y = nan(floor(length(x)/average_factor),1);
for k = 1:floor(length(x)/average_factor)
    y(k) = ...
        10*log10(mean(10.^(double(x((k-1)*average_factor+1:k*average_factor))/10)));
end
