Joint Source Channel Coding for Fading Channel: The Broadcast Approach-Expected Distortion, Gaussian Source and Channel
We consider the problem of transmitting a Gaussian source on a slowly fading Gaussian channel, subject to the mean squared error distortion measure. The channel state information is known only at the receiver but not the transmitter. The source is assumed to be encoded in a successive refinement manner, and then transmitted over the channel using the broadcast strategy. In order to minimize the...
متن کاملJoint source-channel coding of a Gaussian mixture source over the Gaussian broadcast channel
Suppose that we want to send a description of a source to two listeners through a Gaussian broadcast channel, where the channel is used once per each source sample. The minimum possible distortion D 2 that the bad receiver can obtain is D 2 = D(C 2), where D() is the distortion-rate function of the source and C 2 is the capacity of the bad channel. We want to nd the smallest achievable distorti...
متن کاملSource-Channel Coding and Separation for Generalized Communication Systems
We consider transmission of stationary and ergodic sources over non-ergodic composite channels with channel state information at the receiver (CSIR). Previously we introduced alternate capacity definitions to Shannon capacity, including the capacity versus outage and the expected capacity. These generalized definitions relax the constraint of Shannon capacity that all transmitted information mu...
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 کاملCombined Source and Channel Coding for Wireless ATM LANs
It is widely recognized that a viable method to provide “anytime, anywhere” communication needs is by means of wireless technologies. In the indoor wireless environment, the 1-2 Mb/s wireless link technology that is currently available from several vendors (for example, WaveLan) will soon be replaced by higher capacities in the near future. For example, several manufacturers plan to develop rad...
