We study the fundamental rate-interference trade-off between full-duplex and half-duplex transmission modes in a two-hop infrastructure-based decode-and-forward relay link. First, we derive closed-form expressions for average end-to-end capacities. Then, we show that it may be better to tolerate some loop interference in the full-duplex mode than to halve the end-to-end symbol rate by allocating two...
This paper presents an innovative approach to distributed estimation which features partial updates of parameter estimations, thereby offering significant reduction in energy consumption in the sensors. The proposed estimation scheme updates only a subset of the parameters at each iteration. This not only reduces data processing complexity, but also reduces the energy required for diffusing the parameter...
We consider a two-hop infrastructure-based relay link with three transmit power allocation methods. Both amplify-and-forward and decode-and-forward protocols are studied. Fundamentally, a relay can operate either in a full-duplex or in a half-duplex mode. The performance in full-duplex relaying is degraded due to loop interference from the relay output to the relay input. On the other hand, the half-duplex...
