Abstract
In communication, we frequently encounter the problem about the trans-mission rate and quantization noise. That is, small quantization noise or high fidelity definitely increases transmission rate, or large quantization noise or low fidelity might require low transmission rate. In our research, we developed a quantization noise feedback technique, with which quantization noise can be reduced greatly at a given transmission rate. We applied this technique in pyramid image coding environment. An error analysis in frequency domain was carried out. Error estimation for pyramid image coding with and without quantization noise feedback was made. Finally, plenty of computer simulation confirms our theoretic claim.
