Abstract :
We consider the problem of receiver design of wideband multiple transmitter/multiple receiver (MTMR) antenna systems (also known as BLAST systems). While a substantial amount of work has dealt in previous years with the so-called narrow-band case, high data rate systems will require large bandwidths to support rates on the order of Mbits/s. We present some novel blind source separation (BSS) techniques which are capable of operating in such dispersive environments.
