Abstract :
In this work we study simple joint source-channel (JSCC) schemes for transmitting k independent Gaussian source samples with different variances over k additive white Gaussian noise (AWGN) channels. The channels shall have an average power constraint, and the distortion measure shall be the average square error. This problem arises in several practical cases, e.g. in transform coding where the output of the decorrelation process is our source, that may have different variances.
