Abstract :
To achieve full transmission rate for complex signals, quasi orthogonal space-time block coding has been proposed while sacrificing the full diversity. However, due to complex channel condition its performance needs to be improved via antenna selection (AS). Moreover, to achieve utterly orthogonal performance against OSTBC, quasi-orthogonal STBC can still be improved combining pre-coding and antenna selection, Here we derive its expression for average signal to noise rate, which can be used as criteria for AS. From results of simulation, the proposed scheme has been verified combing pre-coding and AS.
