Near-capacity performance may be achieved with the aid of iterative decoding, where
extrinsic soft information is exchanged between the constituent decoders in order to improve …

Mutual information transfer characteristics of soft in/soft out decoders are proposed as a tool
to better understand the convergence behavior of iterative decoding schemes. The …

MIMO-OFDM for LTE, WIFI and WIMAX: Coherent versus Non-Coherent and Cooperative
Turbo-Transceivers provides an up-to-date portrayal of wireless transmission based on …

When mobiles cannot support multiple antennas due to size or other constraints,
conventional space-time coding cannot be used to provide uplink transmit diversity. To …

We introduce a simple technique for analyzing the iterative decoder that is broadly
applicable to different classes of codes defined over graphs in certain fading as well as …

We develop a unified performance metric and detailed analysis for hybrid automatic repeat
request (HARQ) schemes based on incremental redundancy (IR) and Chase combining …

We present a new algorithm for computing the free distance d/sub free/of parallel and
serially concatenated codes with interleavers, the parameter that dominates the code …

This paper introduces a family of error-correcting codes called zigzag codes. A zigzag code
is described by a highly structured zigzag graph. Due to the structural properties of the …

Polarization-adjusted convolutional (PAC) codes were recently proposed and arouse the
interest of the channel coding community because they were shown to approach theoretical …

We propose a new turbo-encoding scheme for high spectral efficiency with performance
close to the Gaussian channel capacity. The scheme combines nonuniform signaling on a …
