ABSTRACT
Recently, double binary circular Turbo code has received
tremendous attention. Due to its better error-correcting
capability than classical Turbo code, it has commenced
practical applications in current communication standards,
such as DVB-RSC and IEEE 802.16 (Wimax). However
current decoding schemes will incur a huge computation
complexity. In this paper, authors present a novel decoding
scheme for double binary circular Turbo codes, which will
not only reduce the computation complexity, but also give at
least 0.5dB performance gain compared with current
