On the Achievable Rate of the Fading Dirty Paper Channel with Imperfect CSIT

The problem of dirty paper coding (DPC) over the (multi-antenna) fading dirty npaper channel (FDPC) Y = H(X + S) + Z is considered when there is imperfect nknowledge of the channel state information H at the transmitter (CSIT). The ncase of FDPC with positive definite (p.d.) input covariance matrix was studied nby th..
