Abstract :
Applying interblock memory to binary linear block codes is a method to increase the transmission reliability by increasing the correlation among codewords. In this paper, we consider short block coding with interblock memory. Since short block codes can be efficiently decoded by employing the A* Algorithm, we investigate the performance of short block coding with interblock memory using the A* decoding. In addition, we propose a simple method which can alleviate the effect of error propagation resulting from interblock memory.
