Abstract: | Time-Varying Variable-Length Error-Correcting (TV-VLEC)codes for joint source-channel coding are introduced. These are codes that use different codebooks according to the symbol position. A sequence MAP decoder for TV-VLEC codes is also derived. It is shown that these codes can maintain a better symbol-level synchronization when compared to standard VLEC codes. A new symbol-constrained free distance measure is also introduced that enables the construction of TV-VLEC codes that out perform standard VLEC codes for the same average codeword length and decoder complexity. Using Monte Carlo simulation it is shown that for a simple 4-symbol code a coding gain of 2dB can be achieved at a frame error rate of 10−3. |
