On iterative receivers for non-coherent channels (2007)
Andrew P. Worthen, Wayne E. Stark
It is well-known that optimal receivers for many wireless communication systems employ joint channel estimation and decoding. Since this is almost always too computationally complex, we consider...
Unified design of iterative receivers using factor graphs (2001)
Andrew P. Worthen, Wayne E. Stark
Abstract — Iterative algorithms are an attractive approach to approximating optimal, but high-complexity, joint channel estimation and decoding receivers for communication systems. We present a...
Low-Density Parity Check Codes for Fading Channels with Memory (1998)
Andrew P. Worthen, Wayne E. Stark
We develop a belief-propagation-based joint decoding and channel state estimation algorithm for low-density parity check codes on fading channels with memory. The excellent empirical performance of...
