Abstract
Space-time block codes are a remarkable modulation scheme
discovered recently for the multiple antenna wireless channel. They have
an elegant mathematical solution for providing full diversity over the
coherent, flat-fading channel. In addition, they require extremely
simple encoding and decoding. Although these codes provide full
diversity at low computational costs, we show that they incur a loss in
capacity because they convert the matrix channel into a scalar AWGN
channel whose capacity is smaller than the true channel capacity. In
this letter the loss in capacity is quantified as a function of channel
rank, code rate, and number of receive antennas
