Hello!
can some body lead me on the reason why ZF equalization of a bit interleaved signal performs worse than ZF equalization of signal that was not bit interleaved. I expect it to be the other way having tried MMSE equalization and recorded interleaving gain of ~2.6 for BER 0f 10e-3.
Cheers!
"uncoded_bits = randi([0 1],1,num_info_bits_per_frame);
%info_bits_per_frame = 1536)
I performed QPSK modulation on it to get 1536/2 complex symbols
after conv with channel freq. response and addition of noise, equalisation and demod,
I got 1536 symbols of + - integers
now i want to convert...
I tried de2bi and wouldn't work. part of data is " 5.1354e-01 -4.8379e-01 -6.4822e-01 6.5347e-01". I used uencode to get it to decimal first but ending up with twice no. of original bits.
