| Abstract: | According to double-binary turbo codes for DVB-RCS, we present a new enhanced decoding technique. Moreover,according to this enhanced algorithm,the author designs hardware architecture of the decoder based on the pipelined technique and gives the timing diagram. Results for ATM and MPEG packets show an improvement of 0.2 dB in BER compared to max-log-map algorithm. |
