tx_add_cyclic_prefix.m

此代码是ＬＤＰＣ码进行BP算法的重要参考代码

function time_signal = tx_add_cyclic_prefix(time_syms)

num_symbols = size(time_syms, 2)/64;
time_signal = zeros(1, num_symbols*80);

symbols = reshape(time_syms, 64, num_symbols);
tmp_syms = [symbols(49:64,:); symbols];

%符号.'表示单纯的转置（非共轭转置）
time_signal = tmp_syms(:).';
