Abstract:

To model the benefit accrued due to limited rate feedback on the information transfer of optimal `input covariance matrices' from a channel-aware receiver to the transmitting users in a multiple-access channel, we study the distortion-rate tradeoff of a source uniformly distributed over multivariate generalizations of PF(n,p2) (the set of positive semi-definite matrices with a trace constraint) and Vn,k ¿ (the classical Stiefel surface) manifolds. Using sphere-packing and random coding arguments, the distortion-rate function is bounded within asymptotically tight limits.
