Abstract :
We present a receiver design for joint interference suppression and equalization of asynchronous multi-user space-time block coded (STBC) systems. We describe the design of front end prefilters to synchronize the received blocks from all users. Simulation results show significant performance improvement for asynchronous transmissions.
