comparison between LCF & OSTBC(Alamouti's code)

in terms of bit error probability alamouti code give best result then LCFA & LCFB in rician faded ch

here we simulate the bit error rate of a 2x2 bpsk modulated mimo system in rician faded channel, for Alamouti's code and Liner complex field A and Liner complex field B code & we make a comparative study.
so what we saw in term of BER Alamouti's code give the best result . LCFB more or less follow Alamouti's code i.e both are very close in BER for a particular SNR . LCFA give the worst perfomance. so for hige data transfer rate and reliability LCFB is preferable
