In this paper, a link adaptation and untrusted relay assignment (LAURA) framework for efficient and reliable wireless cooperative communications with physical layer security is proposed. Using sharp channel codes in different transmission modes, reliability for the destination and security in the presence of untrusted relays (low probability of(More)
The over-provisioning of capacities in optical networks is not a sustainable approach in the long run. In this paper, we propose a software defined networking scheme for quality of service provisioning through energy efficient assignment of optical transponders, employing bandwidth variable distance adaptive modulation and coding. Our scheme enables(More)
Adaptive optical transceivers are considered among the candidates for future optical communications, especially in long-haul and metro applications. In this paper, the hardware requirements of the adaptive digital coherent transceivers are studied. Challenges and solutions for power-efficient implementation of the electro-optical front-end and digital(More)
