PAPR Reduction of Optical OFDM Systems with Exponential Companding Transform and Zero Padding

Creator:

Chen, Deyan

Abstract:

Optical wireless communication (OWC) is an alternative to radio frequency (RF)communication with a signi cantly larger and unregulated spectrum. In OWC systems, optical orthogonal frequency division multiplexing (O-OFDM) with intensity modulation and direct detection (IM/DD) is commonly used. There are two common signal structures in most OWC systems based on...

Malicious-proof and fair credit-based resource allocation techniques for DSA systems

Creator:

AlShammari, Tamara

Abstract:

In this paper, we propose a credit-based resource allocation technique for dynamic spectrum access (DSA) systems that is robust against malicious and selfi sh behaviors and ensures good overall system fairness performance while also allowing spectrum users to achieve high amounts of service. We also propose a new objective function...

Resource allocation methods for quality-of-service provisioning in heterogeneous wireless networks

Creator:

Chakchouk, Nessrine

Abstract:

The increased use of mobile wireless devices that we have recently been witnessing, such as smartphones, tablets, e-readers, and WiFi enabled devices in general, is driving an unprecedented increase in the amount of data traffic. This fast market adoption of the wireless technology along with the tremendous success of multimedia...

Dissertation
Network coding in relay networks

Creator:

Alban, Eduardo

Abstract:

Transmission over wireless networks presents multiple technical challenges due to noise, interference, fading, power constraints and bandwidth limitation. Different solutions have been propposed to overcome these issues and some of them are treated here. Cooperative diversity has been proposed as an implementation for networks where terminals are restricted to using...
