Abstract

In this paper we study the effects of transmission noise on fixed-length coded wavelet coefficients. We extend our previous work on maximum a posteriori detectors [1] to include interbitplane information and determine which transmitted codeword was most likely corrupted into a received erroneous codeword. We present a simple method of recovering from these errors once detected and demonstrate our restoration methodology on scalar-quantized wavelet coefficients that have been transmitted across a binary symmetric channel.
