Wyner-Ziv coding of continuous sources with uncertain side information quality is defined by modeling the correlation noise as a Gaussian-mixture. The analysis of the theoretical rate-distortion performance is presented, along with a coding solution not relying on the presence of a feedback channel. The attainable performance of the coding scheme is derived, and a brief discussion on implementation issues concludes the paper.
