What is BLAST (Bell Labs Layered Space Time)?

BLAST was established by Gerard Foschini at Lucent Technologies’ Bell Laboratories. Bell Laboratories Layer Space-Time (BLAST) is a transceiver architecture for providing spatial multiplexing over multiple-antenna wireless communication systems. BLAST is a spectrally efficient algorithm applied to wireless communication which utilizes the spatial dimension (SDM) to communicate and get diverse information streams utilizing various multiple antennas.
