ROBUST LINEAR CODING IN CONTINUOUS-TIME COMMUNICATION SYSTEMS IN THE PRESENCE OF JAMMING AND WITH NOISY SIDE INFORMATION AT THE DECODER.

This paper develops a robust linear encoding-decoding scheme for the transmission of a sequence of identically distributed independent Gaussian random variables over a stochastic channel with a noiseless feedback link, with noisy side information at the decoder and in the presence of jamming. Both the main and side channels are assumed to be continuous white-Gaussian, and the jamming noise is allowed to be correlated with the channel input, under a given power constraint. The derived encoder is robust in the sense that it secures a minimum performance bound for the communication system, regardless of the probability distribution of the unknown noise process.
