Compress-and-forward on a multiaccess relay channel with computation at the receiver
2013 IEEE International Conference on Communications (ICC), 2013We study a system in which two sources communicate with a destination with the help of a half-duplex relay. We consider a decoding strategy, based on the compute-and-forward strategy, in which the destination decodes two integer-valued linear combinations that relate the transmitted codewords.

An Optimality-Robustness Tradeoff in the Compress-and-Forward Relay Scheme
2010 IEEE 72nd Vehicular Technology Conference - Fall, 2010The compress-and-forward relay scheme developed by (Cover and El Gamal, 1979) is modified by realizing that it is not necessary for the destination to decode the compressed observation of the relay; and even if the compressed observation is to be decoded, it can be more easily done by joint decoding with the original message, rather than in a ...

Compressing IP forwarding tables with fast and bounded update
2015 IEEE 23rd International Symposium on Quality of Service (IWQoS), 2015The size of Forwarding Information Base (FIB) maintained at backbone routers is experiencing an exponential growth, and various solutions have been proposed in the literature. The main shortcoming of FIB compression is the update overhead. Only when the update speed of FIB compression algorithms is sufficiently fast and bounded, the probability of ...

Decode-Compress-and-Forward with Selective-Cooperation for Relay Networks
IEEE Communications Letters, 2012We propose a new signal-processing scheme, referred to as Decode-Compress-and-Forward with Selective-Cooperation (DCF-SC). In DCF-SC, the relay dedicates a certain amount of time to listen to the message broadcasted by the source and then performs Soft-Input Soft-Output (SISO) decoding.

A decoding procedure for compress-and-forward and quantize-and-forward relaying
2012 50th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2012In this paper, a decoding procedure is developed for both the compress-and-forward (CF) and the short message quantize-and-forward (QF-SM) relaying schemes. This procedure is based on exploiting a common feature of the mapping used by both schemes to determine the relay output from the estimate of its input.

Packet-wise compression and forwarding of industrial network captures
2017 9th IEEE International Conference on Intelligent Data Acquisition and Advanced Computing Systems: Technology and Applications (IDAACS), 2017Network traffic captures are necessary for a variety of security applications like identification of malicious patterns or training of intrusion detection systems. While monitoring of enterprise networks is common practice, it is rarely done for industrial production environments due to low bandwidth, confidential production data and sensitive legacy ...

Multi-level compress and forward coding for half-duplex relays
2012 IEEE Global Communications Conference (GLOBECOM), 2012This paper presents a multi-level compress and forward coding scheme for a three-node relay network in which all transmissions are constrained to be from an M-ary PAM constellation. The proposed framework employs a uniform scalar quantizer followed by Slepian-Wolf coding at the relay.

On the Performance of Compressed Interference Forwarding for Uplink Base Station Cooperation
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009The capacity of today's cellular mobile communications systems is mainly limited by inter-cell interference. Multi-cell joint transmission or joint detection schemes are means to overcome this limitation and to actively exploit signal propagation across cell borders rather than treating it as noise.

Path compression in forwarding-based reliable mobile agent communications
2003 International Conference on Parallel Processing, 2003. Proceedings., 2003We concern with the design of efficient algorithms for mobile agent communications. We first describe a novel mailbox-based scheme for flexible and adaptive message delivery in mobile agent systems and a specific adaptive protocol derived from the scheme. Then we present the design and verification of a path compression and garbage collection algorithm

Decode-compress and forward relay: AWGN and constellation constrained channels
2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2017Even though there exists a lot of different transmission techniques, the capacity of the general relay channel is still unknown. This paper shows that combining decode-and-forward (DF) with compress-and-forward (CF) can have a performance advantage over each of the two techniques individually.
