Thread Subject: linear dispersive code

i make my research on 2x2 MIMO system using signal processing named linear dispersive code(combination of 4 input symbols drawn from 4-PSK),the received signal(8 output) can be written as 8x8 channel matrix multiply by 8 x1 signal matrix(8 symbols).the main task is to use ML or sphere decoding(for BER computing) and according to some authors ,this can be done following OSTBC(orthogonal space-time block code)combiner with 8 output signal. i need help please.

Ask your supervisor.

Your post is so full of jargon and acronyms, I don't understand a word
of it.
But your title makes sense:
linear - means simple harmonic motion - superposition works!!!
dispersive - means that motion depends on frequency or wave number and
there exists a relationship between space and time (the dispersion
relation).

So why don't you write your message in plain English.
Maybe you'll get a response.
