A significant amount of recent research has focused on characterizing the diversitymultiplexing tradeoff region in multiple antenna wireless systems. In this paper we focus on finding the point on this diversity-multiplexing region that minimizes endto-end distortion. Our goal is to find the optimal balance between the increased data rate provided by multiplexing versus the error protection pro...

Two common source-channel coding strategies, joint and tandem, are compared on the basis of distortion vs. delay by analyzing specific representatives of each when transmitting analog data samples across a binary symmetric channel. Channel-optimized transform coding is the joint sourcechannel coding strategy; transform coding with Reed-Solomon coding is the tandem strategy. For each strategy, f...

We propose a coding scheme based on the use of systematic linear codes with low-density generator matrix (LDGM codes) for channel coding and joint source-channel coding of multi-terminal correlated binary sources. In both cases, the structures of the LDGM encoder and decoder are shown, and a concatenated scheme aimed at reducing the error floor is proposed. Several decoding possibilities are in...

In this work we characterize the rate-distortion function of a Wyner-Ziv source, depending on an arbitrarily varying state, known non-causally at the encoder. We then consider the problem of joint source-channel coding of this source transmitted over an arbitrarily varying Gel’fand-Pinsker channel, where we assume that one jammer controls both, the source state sequence and the channel state se...

The combination of source coding with decoder side-information (Wyner-Ziv problem) and channel coding with encoder side-information (Gel’fand-Pinsker problem) can be optimally solved using the separation principle. In this work we show an alternative scheme for the quadratic-Gaussian case, which merges source and channel coding. This scheme achieves the optimal performance by a applying modulo-...

Joint source and channel coding (JSCC), multicarrier modulation (MCM) and diversity are some key techniques for the multimedia transmission over wireless channels. In this work, we first investigate the channel estimation problem for the MCM system with multiple transmitter antennas. A model based channel estimation approach is proposed to identify the multiple channels simultaneously. We then ...

In this paper, a wireless channel is viewed as a heterogeneous network in the time domain, and an adaptive video transmission scheme for H.264 scalable video over wireless channels modeled as a finite-state Markov chain processes is presented. In order to investigate the robustness of adaptive video transmission for H.264 scalable video over wireless channels, statistical channel models can be ...
