Joint source-channel coding for a quantum multiple access channel
Suppose that two senders each obtain one share of the output of a classical, bivariate, correlated information source. They would like to transmit the correlated source to a receiver using a quantum multiple access channel. In prior work, Cover, El Gamal, and Salehi provided a combined sourcechannel coding strategy for a classical multiple access channel which outperforms the simpler “separatio...
متن کاملCoding for a Multiple Access OR Channel: a Survey
The signature coding for M active users out of T total users over a multiple access OR channel is considered. The mathematical problem is equivalent to the M -coverfree problem of extremal set theory. We survey the upper and lower bounds on the minimal code word length n(T,M), and present some code constructions. According to the current state of the theory, for 1 M T 1 2 M2 logM log T ≤ n(T,M)...
متن کاملCoding for a Noisy Binary Multiple-access Adder Channel
Multip le-access adder channels have been extensively studied for manyyears. They can be classified into several types. The type of channels weconsider in this paper is discrete,memory less, synchronized and noisy. On noisy multip le-access adder channels a receiver must derive a groupof transmitted codewords uniquely from a received word garbled by errors. This means that a code suitable for t...
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 کاملNetwork coding schemes for the multiple-access relay channel
We examine and compare four different joint-network-channel-codes (JNCC) and three reference systems for the multiple-access relay channel (MARC) with block Rayleigh fading channels for symmetric and asymmetric setups. Two of the JNCC’s were presented previously in the literature and the other two are novel approaches. The JNCC’s outperform the reference systems and achieve a diversity gain for...
