In this paper, the combination of equalization and turbo decoding is studied. In the iterative decoding of a product code in block turbo coding system, the equalization process is performed within the iteration loop. The present study aims to investigate the decision feedback equalizer (DFE) incorporated in the iterative decoding. Simulation results show that the more severe the channel interfe...

Unrehearsed spoken language often contains disfluencies. In order to correctly interpret a spoken utterance, any such disfluencies must be identified and removed or otherwise dealt with. Operating on transcripts of speech which contain disfluencies, our particular focus here is the identification and correction of speech repairs using a noisy channel model. Our aim is to develop a high-accuracy...

Capacity of dense coding via correlated noisy channel is greater than that uncorrelated channel. It shown the weak measurement and reversal need to further improve their quantum capacity in amplitude damping channel, but this improvement very small phase depolarizing

MIMO wireless systems have received a great deal of attention recently, in part due to the promise of increased throughput, extended range, and improved reliability. Achieving the gains of the MIMO channel requires coding that can take advantage of these channel resources. This work studies the performance of different concatenated space-time coding and outer channel coding and develops some pr...

A new integrated framework for source and channel rate allocation is presented for video coding and transmission over wireless channels without feedback channels available. For a fixed total channel bit rate and a finite number of channel coding rates, the proposed scheme can obtain the near-optimal source and channel coding pair and corresponding robust video coding scheme such that the expect...

A new approach to joint source–channel coding is presented in the context of communicating correlated sources over multiple access channels. Similar to the separation architecture, the joint source– channel coding system architecture in this approach is modular, whereby the source encoding and channel decoding operations are decoupled. However, unlike the separation architecture, the same codew...

Source vs. Channel coding • Source coding: represent the source information with the minimum of symbols • Channel coding: represent the source information in a manner that minimizes the error probability in decoding

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...

There has been an interesting issue in multimedia communications over wireless system in recent years. In order to achieve high data rate wireless multimedia communications, spatial multiplexing technique (Foschini & Gans, 1998; Wolniansky et al. 1998) has recently developed as one of the most noteworthy techniques as multiple-input and multiple-output (MIMO) systems. If the channel state infor...
