1. Tales of Tailbiting Codes
Abstract : Tailbiting codes are error correcting codes and can be used in digital transmission systems. They are obtained by terminating convolutional codes into block codes. This thesis consists of an introduction to convolutional and tailbiting codes, and the Papers A--G that include the main results. READ MORE

2. On the Construction and Analysis of Iteratively Decodable Codes
Abstract : Iterative decoding methods allow efficient decoding of long codes that are composed of smaller component codes. As a result reliable communication can be achieved with low decoding complexity even for rates close to Shannon capacity. This makes iteratively decodable codes a very attractive object of study in modern coding theory. READ MORE

3. On hard-decision forward error correction with application to high-throughput fiber-optic communications
Abstract : The advent of the Internet not only changed the communication methods significantly, but also the life-style of the human beings. The number of Internet users has grown exponentially in the last decade, and the number of users exceeded 3.4 billion in 2016. READ MORE

4. On Spectrally Efficient Continuous Phase Modulation
Abstract : Spectrally efficient partial response continuous phase modulation (CPM)for wireless links is considered. Continuous phase modulation defines constantenvelope phase codes, which are advantageous when using non-linear amplifiers. READ MORE

5. A covariance structure analysis approach to the errors-in-variables estimation problem
Abstract : It is a well-known fact that standard regression techniques, when applied to errors-in-variables (EIV) models, lead to biased and inconsistent parameter estimation. The work presented in this thesis address the EIV estimation problem using covariance structure analysis (CSA). READ MORE
