Incremental rate maximisation power loading with BER improvements [PDF]
, 2010 This paper aims to maximise the rate over a MIMO link using incremental power and bit allocation. Two different schemes, greedy power allocation (GPA) and greedy bit allocation (GBA), are addressed and compared with the standard uniform power allocation (

Adaptive Mode Selection and Power Allocation in Bidirectional Buffer-aided Relay Networks
, 2013 In this paper, we consider the problem of sum rate maximization in a bidirectional relay network with fading. Hereby, user 1 and user 2 communicate with each other only through a relay, i.e., a direct link between user 1 and user 2 is not present.

OAM multiple transmission using uniform circular arrays: numerical modeling and experimental verification with two digital television signals [PDF]
, 2016 In this work we present the outcomes of a radio-frequency OAM transmission between two antenna arrays performed in a real-world context. The analysis is supplemented by deep simulative investigations able to provide both a preliminary overview of the ...
