We study the transmission of correlated sources over multiple-access-relay channels, in which both the relay and the destination have access to side information arbitrarily correlated with the sources. We propose two new joint source-channel coding schemes based on novel combinations of the correlation preserving mapping (CPM) technique with Slepian-Wolf (SW) source coding. The proposed coding schemes are based on the decode-and-forward strategy in which CPM is used for encoding information simultaneously to the relay and to the destination, whereas the cooperation information from the relay is transmitted using SW coding. The two schemes differ in the decoding method used at the destination: While the first scheme uses successive backward decoding, the second uses simultaneous backward decoding. We show that none of the schemes can be proved to be universally superior, but both schemes achieve the best known results in all the special cases previously considered. © 2012 IEEE.

Energy harvesting has emerged as a powerful technology for complementing current battery-powered communication systems in order to extend their lifetime. In this paper a general framework is introduced for the optimization of communication systems in which the transmitter is able to harvest energy from its environment. Assuming that the energy arrival process is known non-causally at the transmitter, the structure of the optimal transmission scheme, which maximizes the amount of transmitted data by a given deadline, is identified. Our framework includes models with continuous energy arrival as well as battery constraints. A battery that suffers from energy leakage is studied further, and the optimal transmission scheme is characterized for a constant leakage rate.

Cocco G, Gunduz D, Ibars C, 2011, Real-time broadcasting over block-fading channels, Pages: 584-588, ISSN: 2154-0217
Broadcast transmission from a base station (BS) to a group of users is studied. It is assumed that the BS receives data at a constant rate and tries to broadcast these messages to the whole set of users within a certain deadline. The channels are assumed to be block fading and independent over blocks and users. Our performance measure is the total rate of received information at the users within the transmission deadline. Three different encoding schemes are proposed, and they are compared with an informed transmitter upper bound in terms of the average total reception rate for a set of users with varying channel qualities. It is shown that no single transmission strategy dominates for all channel settings, and the best broadcasting technique depends on the distribution of the average channel conditions over the users. © 2011 IEEE.

Two new schemes are proposed for collision resolution in slotted ALOHA networks based on multi-user physicallayer network coding (MU PHY NC). In the proposed random access schemes, a collision of a generic number of packets can be recovered decoding the XOR of the original messages, such that the signal resulting from the collision is exploited rather than being discarded. Two different schemes that differ in terms of the amount of control information that needs to be transmitted from the access point, are studied. © 2011 IEEE.

Gündüz D, Erkip E, Goldsmith A, et al., 2010, Cooperative relaying in sensor networks
Reliable transmission of a discrete memoryless source over a multiple-relay network is considered. Motivated by sensor network applications, it is assumed that the relays and the destination all have access to side information correlated with the underlying source signal. Joint source-channel cooperative transmission is studied in which the relays help the transmission of the source signal to the destination by using both their overheard signals, as in the classical channel cooperation scenario, and the available correlated side information. Decode-and-forward (DF) based cooperative transmission is considered in a network of multiple relay terminals and two different achievability schemes are proposed: i) a regular encoding and sliding-window decoding scheme with no binning at the encoder, and ii) a semi-regular encoding and backward decoding scheme with explicit binning based on the side information statistics. It is shown that both of these schemes lead to the same sufficiency conditions, which are shown to be also necessary in the case of a physically degraded relay network in which the side information signals are also degraded in the same order.
Jain A, Gündüz D, Kulkarni SR, et al., 2010, Energy-distortion tradeoffs in multiple-access channels with feedback
The energy-distortion function E(D) for the joint source-channel coding problem in networks is defined and studied. The energy-distortion function E(D) is defined as the minimum energy required to transmit a source to a receiver within the target distortion D, when there is no restriction on the number of channel uses per source sample. For point-to-point channels, E(D) is shown to be equal to the product of the minimum energy per bit Ebmin and the rate-distortion function R(D), establishing the optimality of source-channel separation in this setting. Then, it is shown that the optimality of separation does not extend to multi-user networks. A scenario with two encoders observing correlated Gaussian sources in which the encoders communicate to the receiver over a Gaussian multiple-access channel (MAC) with perfect channel output feedback is studied. First a lower bound on E(D) is provided and compared against an upper bound achievable by separation. Even though the separation based scheme does not achieve the lower bound in general, its energy requirement is shown to be within a constant gap of E(D) in the low distortion regime, for which the energy requirement grows unbounded. Another upper bound using uncoded transmission based on the well-known Schalkwijk-Kailath (SK) scheme is also considered. Through simulation, it is shown that this scheme outperforms the separation based scheme in various scenarios, thus establishing the sub-optimality of separation in this model of multiple users with correlated sources.
