1. Capabilities of Convolutional Codes: Unequal Error Protection and More
Sammanfattning : Many communication systems obtain enhanced performance by using concatenated coding schemes. Turbo codes and woven convolutional codes are two examples of such schemes. LÄS MER
2. Topics in applied mathematics -- error-correcting codes and homogenization of PDE
Sammanfattning : .... LÄS MER
3. Optimization, Matroids and Error-Correcting Codes
Sammanfattning : The first subject we investigate in this thesis deals with optimization problems on graphs. The edges are given costs defined by the values of independent exponential random variables. We show how to calculate some or all moments of the distributions of the costs of some optimization problems on graphs. LÄS MER
4. On the Design of Error Control Coding for Wireless Communication Systems
Sammanfattning : New wireless services such as mobile Internet, multimedia streaming and high speed packet data access are making their way to the market. Availability of low-cost equipment providing high transmission quality and efficient spectrum utilization is crucial to the success of these services. LÄS MER
5. Analysis and Design of Spatially-Coupled Codes with Application to Fiber-Optical Communications
Sammanfattning : The theme of this thesis is the analysis and design of error-correcting codes that are suitable for high-speed fiber-optical communication systems. In particular, we consider two code classes. The codes in the first class are protograph-based low-density parity-check (LDPC) codes which are decoded using iterative soft-decision decoding. LÄS MER
