1. Adaptive Concatenated Coding for Wireless Real-Time Communications
Abstract : The objective of this thesis is to improve the performance of real-time communication overa wireless channel, by means of specifically tailored channel coding. The deadlinedependent coding (DDC) communication protocol presented here lets the timeliness and thereliability of the delivered information constitute quality of service (QoS) parametersrequested by the application.

2. Convergence Analysis and Design of Multiple Concatenated Codes
Abstract : The objective of this thesis is to develop a methodology for designing efficient multiple concatenated coding schemes, consisting of two or more constituent codes, concatenated in serial or in parallel. Extrinsic information transfer (EXIT) analysis is found to be a suitable and versatile analysis tool for such codes and thus, the design methodology is based almost entirely on this technique.

3. Iterative receivers with channel estimation for MIMO and multi-user OFDM systems
Abstract : The traffic in wireless networks has been showing an exponential growth over the last decade. In order to meet the demand, and support a continuation of this growth, the scarce radio resources need to be efficiently used. READ MORE

4. Preliminary Design Investigations for the Selection of Optimum Reaction Degree for 1st Stage of a High Pressure Gas Turbine
Abstract : One-dimensional (1D) turbine design calculation phase requires a handful of input data and choice of design parameters to provide the blade flow path geometry along with the flow kinematics and thermodynamics properties at the blade mid-span. The choice of important aerodynamics design parameters namely reaction degree, nozzle guide vane NGV exit flow angle or flow coefficient and stage loading defines the mid-span flow velocity triangles.

5. Multiuser Serially Concatenated Continuous Phase Modulation
Abstract : A multiuser communication system using serially concatenated and randomly interleaved continuous phase modulation (SCCPM) over the additive white Gaussian noise (AWGN) channel is investigated. The users, which may be asynchronous, are allowed to have individual energy levels as well as carrier frequencies and phases. READ MORE
