Evolution of prior information in SISO equalization

Research output: Contribution to journalArticlepeer-review


Soft-input soft-output (SISO) devices play as important role in a variety of algorithms for communications problems. In an iterative structure, soft information is passed between a number of SISO devices, and the ensemble of the soft information evolves with each iteration. We develop and present a framework for analyzing the evolution of this soft information in a class of SISO linear equalizers.
