I. Introduction
We consider a communication system which employs LT
transmit and LR receive antennas. The channel is assumed to
be quasistatic Rayleigh
at fading. It is assumed that only
the receiver has knowledge of the path gains. The additive
noise at receiver j at symbol interval t, N j
t , is assumed to be
complex Gaussian with i.i.d. real and imaginary parts. Linear
propagation is assumed, so that for a CSNR of
s at each
receive antenna, the signal at receive antenna j can be written
as R j
t =
q
s
