3.4 Words-to-bits (receiver) (matlab)

%% Words to Bits (RECEIVER) % ------------------------------------------------------------------------% Description: This module simply takes the demodulated words and expands % them into a bit stream for ease of comparison.% % Inputs: words - Group of bits% Outputs: bits - Bit streamfunction bits = w2b(words) %%num_subcarriers = size(words,1); % Implicit number of subcarriers bits_per_symbol = size(words,2); % Implicit bits per symboltotal_bits = bits_per_symbol*num_subcarriers; % Total number of bits bits = zeros(1,total_bits);for n=1:num_subcarriersfor m=1:bits_per_symbol bits((n-1)*bits_per_symbol+m) = words(n,m); % Separate one by oneend endend
