1. Interference Cancellation for DS/CDMA Systems in Flat Fading Channels
Abstract : This thesis investigates interference cancellation in direct-sequence codedivision multiple access (DS/CDMA) systems that support multiple data rates.Two approaches for implementing multiple data rates are considered. Oneis the use of mixed modulation. The second is the use of parallel channels. READ MORE

2. Structural elements involved in protein-mediated proton transfer : Implications from studies of cytochrome c oxidase
Abstract : Proton transfer is one of the most common reactions in biological systems. During energy conversion inside a cell, proton transfer is crucial to maintain an electrochemical proton gradient across the cell membrane. This gradient is in turn used to e.g. READ MORE

3. Successive Interference Cancellation in DS-CDMA Systems
Abstract : There is every indication that direct-sequence code division multiple access (DS-CDMA) will be one of the multiple access schemes for the third generation wireless mobile systems. CDMA is a flexible multiple access method suitable for supporting many new services (speech, data, video, etc), which are becoming increasingly important for mobile communications. READ MORE
