comparative study between 2x2 and 4x4 bpsk modulated system in rician faded channel

for higher antenna system in MIMO wireless coding system is less matter in terms of BER

here we made a comparative study the bit error probability between 2x2 and 4x4 ,bpsk modulated system for both linear complex field coding A & B (i.e LCFA & LCFB) in rician faded channel.

what we found that in case of 2x2 antenna system LCFA & LCFB dose matter in terms of bit error probability. LCFB gives a much better result then LCFA in case of ML(maximum likelihood ) decoding . but when we move to 4x4 antenna system we saw it really doesn't matter . because as we go higher system receiver got much more coded signal for a particular signal then the lower Oder system for deciding the original massage .
