Interference Reduction in Single Hop Relay Networks
The purpose of this paper is to determine the possible capacity increase in single hop relay networks, where mobile stations are enabled to serve as additional access points for other terminals. The total power used for direct transmission from a central base station to uniformly distributed mobiles is compared with indirect transmission using mobiles as relay nodes for different path loss expo...
متن کاملThe Expected Achievable Distortion of Two-User Decentralized Interference Channels
This paper concerns the transmission of two independent Gaussian sources over a two-user decentralized interference channel, assuming that the transmitters are unaware of the instantaneous CSIs. The availability of the channel state information at receivers (CSIR) is considered in two scenarios of perfect and imperfect CSIR. In the imperfect CSIR case, we consider a more practical assumption of...
متن کاملA distributed algorithm using interference pricing for relay interference channels
Relays in cellular systems are sensitive to interference. A good relay design will transmit in a way that avoids excess out-of-cell interference. This article proposes a two-step algorithm for relay design for the relay interference channel, which models a relay-based cellular system. The transmitters and relays are equipped with multiple antennas while the receivers are equipped with a single ...
متن کاملOblivious Relaying for Primitive Interference Relay Channels
1Consider a relay node that needs to operate without knowledge of the codebooks (i.e., modulation, coding) employed by the assisted source-destination pairs. This paper studies the performance of relaying under this condition, termed oblivious relaying, for the primitive relay channel (PRC) and the primitive interference relay channel (PIRC). "Primitive" refers to the fact that the relay-to-des...
متن کاملInterference Relay Channels - Part I: Transmission Rates
We analyze the performance of a system composed of two interfering point-to-point links where the transmitters can exploit a common relay to improve their individual transmission rate. When the relay uses the amplify-and-forward protocol we prove that it is not always optimal (in some sense defined later on) to exploit all the relay transmit power and derive the corresponding optimal amplificat...
