1. MIMO Decoding Algorithm and Implementation
Abstract : Multi-Input Multi-Output system has been one of the hot technologies for future wireless communications, since it can increase the capacity (coverage or link quality in other senses) at no cost in frequency spectrum. This doctoral thesis investigates improvements to MIMO decoding algorithms and presents VLSI implementation results. READ MORE

2. Trellis Decoding: From Algorithm to Flexible Architectures
Abstract : Trellis decoding is a popular method to recover encoded information corrupted during transmission over a noisy channel. Prominent members of this class of decoding algorithms are the Viterbi algorithm, which provides maximum likelihood estimates, and the BCJR algorithm, which is a maximum a posteriori estimator commonly used in iterative decoding.

3. Low-Power Clocking and Circuit Techniques for Leakage and Process Variation Compensation
Abstract : Over the last four decades the integrated circuit industry has evolved in a tremendous pace. This success has been driven by the scaling of device sizes leading to higher and higher integration capability, which have enabled more functionality and higher performance. READ MORE

4. Custom Designed Digital Signal Processors Using Bit-Serial Arithmetic
Abstract : This thesis presents two prime contributions. First, digital filters for both intermediate and base band filtering for mobile communication are presented. Second, a local clock for on-chip clock generation is introduced. The intermediate frequency filter is a digital alternative to today's analog filters. READ MORE

5. Concurrent chip and package design for radio and mixed-signal systems
Abstract : The advances in VLSI and packaging technologies enable us to integrate a whole system on a single chip (SoC) or on a package module. In these systems, analog/RF electronics, digital circuitries, and memories coexist. This new technology brings us new freedom for system integration as well as new challenges in system design and implementation. READ MORE
