Implementation of iterative Joint algorithm for phase recovery and turbo decoding on TigerSHARC DSP

摘要

The paper describes iterative algorithm of joint synchronization and decoding of the turbo coded BPSK, QPSK and MQAM signals. SOVA and the Maximum likelihood estimation of the phase error is used in a joint algorithm, phase derotation is performed with using a CORDIC algorithm. Proposed algorithm was implemented on TigerSHARC digiral signal processor by Analog Devices.
