Abstract :
A novel adaptive threshold-decoding algorithm for block turbo codes (BTCs) was proposed. Simulations for a few combinations of BCH codes were carried out with the proposed algorithm and Chase algorithm for the purpose of comparison. The error correction performance with the suggested algorithm was negligibly degraded comparing with that using the Chase algorithm while it gained 1 dB at BER=10-4 against Fragiacomo et al.´s results. Furthermore, the suggested algorithm reduced the number of codewords to be searched and speeded up the decoding process
