Combined interference suppression and frequency domain equalization for space-time block coded transmission

We present a transmission scheme that combines space-time block coding over frequency selective channels with single carrier frequency domain interference suppression and equalization. The equalization and interference suppression exploits the structure of the space-time block coding. It is shown that this scheme will provide the diversity benefit of both the frequency selective channel and the space-time block code while completely suppressing the interference from another co-channel transmitter that occupies exactly the same channel (time & frequency) as the desired transmitter.
