Abstract :
In this paper we study the analog transmission of discrete-time continuous-amplitude sources over MIMO Rayleigh fading channels at extremely high data rates. Linear and Decision Feedback MMSE MIMO receivers are used to transform the MIMO channel into several SISO channels. We assume the presence of a limited feedback channel that allows continuous adaptation of the encoder parameters to the time-varying channel SNR. Experimental results show that the decision feedback MIMO receiver performs at 2 dB from the theoretical bound when transmitting Gaussian sources.
