Power Extrinsic Propagation for Turbo-Codes

A generalized information passing strategy is discussed for iterative decoding of turbo-like systems. Both the existence of fixed point and the convergence of the iterative process are analyzed. It is proved that convergence can always be obtained. The added degree of freedom provides advantages ove...

Beschreibung
Zusammenfassung:	A generalized information passing strategy is discussed for iterative decoding of turbo-like systems. Both the existence of fixed point and the convergence of the iterative process are analyzed. It is proved that convergence can always be obtained. The added degree of freedom provides advantages over the classical algorithm in terms of convergence or BER.
