摘要: In many communication applications one is interested in transmitting a time-discrete analog-valued (i.e. continues alphabet) source over analog channel. We study this problem the case of bandwidth expansion, sense that sample, X, transmitted N orthogonal channels. An source-channel code based on polynomials proposed and analyzed. The can be generated using Gram-Schmidt procedure, to fit virtually any distribution.
