rx_deinterleave.m

现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFT/DFT,同步(时间/频率同步)和信道估计,以及频率偏移的估计等一系列代码.希望大家能从中得到你需要的东西.

function out_bits = rx_deinterleave(in_bits, sim_options)

global sim_consts;

interleaver_depth = sim_consts.NumDataSubc * get_bits_per_symbol(sim_options.Modulation);
num_symbols = length(in_bits)/interleaver_depth;

single_deintlvr_patt = rx_gen_deintlvr_patt(interleaver_depth);

deintlvr_patt = interleaver_depth*ones(interleaver_depth, num_symbols);
deintlvr_patt = deintlvr_patt*diag(0:num_symbols-1);
deintlvr_patt = deintlvr_patt+repmat(single_deintlvr_patt', 1, num_symbols);
deintlvr_patt = deintlvr_patt(:);

out_bits(deintlvr_patt) = in_bits;
