SMART Infrastructure Facility - Papers
The acquisition of complex software intensive systems is fraught with significant risks and often incurs schedule delays, cost overruns and reduced functionality when the product is finally delivered. This paper presents a model to assess the effectiveness of software intensive acquisitions, founded on the premise that the solution depends on a series of transformations that transform input products in one domain into output products in another domain. Transformations are performed by people, and require knowledge and skills pertinent to both input and output domains. Ideally, products should be transformed without distortions resulting into the desirable solution. In reality, distortions occur …

Evolution Analysis Of Iterative Lmmse-App Detection For Coded Linear System With Cyclic Prefixes, Xiaojun Yuan, Qinghua Guo, Li Ping
Faculty of Engineering and Information Sciences - Papers: Part A
This paper is concerned with the iterative detection principles for coded linear systems with cyclic prefixes. We derive a matrix-form low-cost fast Fourier transform (FFT) based iterative LMMSE-APP detector and propose an evolution technique for the performance evaluation of the proposed detector. Numerical results show a good match between simulation and evolution prediction. ©2007 IEEE.
