Abstract
Transmit diversity through two-transmit and
one-receive antennas (DISO) with Alamouti's
Space-Time block coding (STBC) assumes the channel
be flat and static over the coding block. Lindskog and
Paulraj have extended this scheme for a time dispersive
channel by doing the space-time coding over a large
data block such as one burst. This helps to achieve
diversity gain on a time-dispersive channel. However,
there are two issues: 1) The receiver front-end consists
of channel response filters and combining followed by a
sequence detector. The channel filters on receive signal
double the channel response size, consequently,
increase the complexity of the sequence detector. 2)
Channel needs to be static over the entire larger block of
coded data as opposed to only two coded-symbol
