FEC Performances in Multimedia Streaming

Pascal Frossard

In this paper, the performances of packet-level media-independent FEC schemes are computed in terms of both packet loss ratio and average burst length of multimedia data after error recovery. The set of equations leading to the analytical formulation of bo ...

On optimal low-complexity source/channel coding

Martin Vetterli, Michael Christoph Gastpar, Bixio Rimoldi

Shannon's separation theorem gives a conceptually and practically appealing way to construct an optimal communication system in two independent steps, namely source compression and channel coding. However, sometimes it is worth considering {\em joint} sour ...

To code or not to code

Martin Vetterli, Michael Christoph Gastpar, Bixio Rimoldi

The theory and practice of digital communication during the past 50 years has been strongly influenced by Shannon's separation theorem. While it is conceptually and practically appealing to separate source from channel coding, either step requires infinite ...

Adaptive Multi-Input Multi-Output Fading Channel Equalization using Kalman Estimation

Ali H. Sayed, Christina Fragouli

his paper addresses the problem of adaptive channel tracking and equalization for multi-input multi-output (MIMO) time-variant frequency-selective channels. A finite-length minimum-mean-squared-error decision-feedback equalizer (MMSE-DFE) performs the equa ...

Symbol interleaved parallel concatenated trellis coded modulation

Christina Fragouli

This paper presents a method for efficient coding at high spectral efficiency using parallel concatenated trellis coded modulation (PCTCM) with symbol interleaving. The constituent encoders are optimized for symbol-wise free distance, and each has an infin ...

Channel estimation and equalization in fading

Ali H. Sayed, Christina Fragouli

This paper addresses the problem of channel tracking and equalization in frequency-selective fading channels. Low-order autoregressive models approximate the channel taps, where each tap is a circular complex Gaussian random process with the typical U-shap ...

Semi-random interleaver design criteria

Christina Fragouli

A spread interleaver of length N is a semi-random interleaver based on the random selection without replacement of N integers from 1 to N under a design constraint. This paper extends the spread-interleaver design method to multiple error events, based on ...

Multiresolution broadcast for digital HDTV using joint source-channel coding

Martin Vetterli

The use of multiresolution (MR) joint source-channel coding in the context of digital terrestrial broadcasting of high-definition television (HDTV) is shown to be an efficient alternative to single-resolution techniques, which suffer from a sharp threshold ...
