Abstract [en]

The problem of source-channel coding over a multiple-antenna channel with quantized channel state information at the transmitter (CSIT) is considered. Upperbounds on the distortion exponents achieved with partial CSIT are developed. The achievable distortion exponent of some hybrid schemes with heavily quantized feedback under both short- and long-term power constraints is also derived. The results demonstrate that excellent performance can be achieved by combining simple schemes with a very coarse feedback link.
