Abstract :
The performance limitation due to imperfect channel estimation in a layered space-time (BLAST) receiver is addressed. For the performance evaluation, the effective signal-to-interference ratio and average bit error rate expressions of zero forcing VBLAST systems with unordered successive cancellation are derived taking into account the effect of imperfect channel information.
