New digital communication applications, such as multimedia, require very powerful error correcting codes that deliver low error rates while operating at low to moderate ratios (SNRs). Turbo codes have reasonable complexity and can achieve very low error rates if a…

In this thesis, we present two new methods to overcome the effects of both camera calibration errors and partial emptiness of surface voxels in voxel-coloring. Voxel-coloring is a relatively new volumetric method for 3D scene reconstruction from multiple calibrated views.…

This thesis considers the design of receivers for multi-user communication systems based on asynchronous direct-sequence code-division multiple-access (DS-CDMA). Its primary aim is to improve current receiver designs which exhibit shortcomings in systems using long sequence spreading (where the spreading sequence…

Wireless digital data system designers have formidable future design challenges in order to provide the mobile user with a quality of service comparable to that of a wireline system in such metrics as responsiveness, quality, and throughput. The goal of…

This dissertation addresses the impact of integrated services on future third generation wireless DS-CDMA networks. The first part of the research characterizes the multiple-access interference (MAI) in an integrated DS-CDMA system. The system model is designed to accommodate bursty packed-based…
