On Turbo-Schedules for LDPC Decoding
de Baynast, Alexandre; Radosavljevic, Predrag; Sabharwal, Ashutosh; Cavallaro, Joseph R.
The convergence rate of LDPC decoding is comparatively slower than turbo code decoding: 25 LDPC iterations versus 8-10 iterations for turbo codes. Recently, Mansour proposed a â turbo-scheduleâ to improve the convergence rate of LDPC decoders. In this letter, we first extend the turbo-scheduling principle to the check messages. Second, we show analytically that the convergence rate of both turbo-schedules is about twice as fast as the standard message passing algorithm for most LDPC codes.
