Joint source-channel subband coding of images
This paper proposes a new adaptive source-channel coding scheme in the context of subband coding. We rst express the total mean-squared distortion su ered by the source in terms of source and channel distortions of the subbands. We then minimize this total distortion by an appropriate choice of source and channel coding rates for the subbands. This corresponds to casting the conventional bit al...
متن کاملAnalog Joint Source Channel Coding for Gaussian Multiple Access Channels
We investigate the problem of transmiting independent sources over the Gaussian Multiple Access Channel (MAC) using a CDMA-like access scheme that allows users to transmit at different rates. Rather than using standard digital communications systems, we focus on analog joint source-channel coding techniques to encode each user’s source. We analyze the performance of the proposed scheme and demo...
متن کاملAnalog joint source-channel coding over MIMO channels
Analog joint source-channel coding (JSCC) is a communication strategy that does not follow the separation principle of conventional digital systems but has been shown to approach the optimal distortion-cost tradeoff over additive white Gaussian noise channels. In this work, we investigate the feasibility of analog JSCC over multiple-input multiple-output (MIMO) fading channels. Since, due to co...
متن کاملAnalog Joint Source-Channel Coding for MIMO-OFDM Systems
Analog Joint Source-Channel Coding (JSCC) has been shown to approach the optimal distortion-cost tradeoff when transmitting over AWGN channels. In this work we consider analog JSCC over frequency-selective channels using Orthogonal Frequency Division Multiplexing (OFDM) modulation and multiple antennas at transmission and/or reception, i.e. using a MIMO-OFDM system. Due to its high complexity, ...
متن کاملMobile image transmission using combined source and channel coding with low complexity concealment
In this paper, we propose an efficient image transmission system for reliable transmission of vulnerable compressed images over mobile radio channels. The image coder is fully compatible with the JPEG baseline coding standard. Its transmission system is designed based on lossy transmission with combined source and channel coding (CSCC) and low complexity error concealment. Specifically, the pro...
