A (layered) broadcast approach is studied for the fading wiretap channel without the channel state information (CSI) at the transmitter. Two broadcast schemes, based on superposition coding and embedded coding respectively, are developed to encode information into a number of layers and use stochastic encoding to keep the corresponding information secret from an eavesdropper. The layers that can be successfully and securely transmitted are determined by the channel states to the legitimate receiver and the eavesdropper. The advantage of these broadcast approaches is that the transmitter does not need to know the CSI to the legitimate receiver and the eavesdropper, …

Univercl 1.0 --- Phase I Of A Complete Opencl Implementation, Phil Pratt-Szeliga, Jim Fawcett
Electrical Engineering and Computer Science - All Scholarship
Recently the Khronos group has released an open specification for OpenCL, the Open Computation Language. OpenCL strives to create a standard language for programming novel computer architectures such as the multi-core CPU, the GPU and accelerators. The programming model is similar to Nvidia's CUDA. UniverCL is a partial implementation of the OpenCL 1.0 Specification that has enough functionality to demonstrate the major components of the specification. It currently includes support for two hardware devices: the multi-core CPU and the Cell Broadband Engine. This technical report captures the work done in Phase I of UniverCL's development and outlines Phase II of …
