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...
Turbo decoders inherently require large hardware for VLSI implementation as a large amount of memory is required to store incoming data and intermediate computation results. Design of highly efficient Turbo decoders requires reduction of hardware size and power consumption. In this paper, finite precision effects on the performance of Turbo decoders are analyzed and the optimal word lengths of variables...
