In this work, we give an overview of the main challenges that must be tackled to perform a joint design of the backhaul and radio access network in a cloud-based mobile network. The deployment of a very dense network based on small cells connected through a heterogeneous backhaul is a realistic way of achieving a high throughput in a mobile network. But,(More)
In this paper we propose an independent channel precoder for orthogonal frequency division multiplexing (OFDM) systems over fading channels. The design of the precoder is based on the information redistribution of the input modulated symbols among the output precoded symbols. The proposed precoder decreases the variance of the instantaneous noise power at(More)
We propose an optimization framework to perform resource allocation in virtual sensor networks. Sensor network virtualization is a promising paradigm to improve flexibility of wireless sensor networks which allows to dynamically assign physical resources to multiple stakeholder applications. The proposed optimization framework aims at maximizing the total(More)
