This work presents an FPGA oriented implementation methodology for the MPEG-4 video decoder based on a hardware/software co-design approach. Procedures and analyses resulting in the proposed partitioning to SW/HW part are described. Simulation results demonstrate deduction of decoder complexity with respect to the implementation in microprocessor.

NGN quality assurance is presented, taking into account both perceptual quality of experience and technology-dependant quality of service issues. The respective procedures, entities, mechanisms and profiles are discussed. The purpose of the presented approach is in research, development and discussion of pursuing the end-to-end controllability of the quality of the multimedia NGN-based communications in an environment that is best-effort in its nature and promotes end-user’s access agnosticism, service agility and global mobility.

A phase detector with a reduced spurious output has been realized. The parallel operation of two conventional phase detectors is presented theoretically and then verified with a practical experiment. Maintaining a phase shift of 90 degrees between the two phase detectors, the spurious output at twice the comparing frequency can be reduced significantly, resulting in a much cleaner output spectrum of the electro-optical PLL synthesizer.

A new method for signal acquisition and post-processing in MR imaging was developed. With the proposed method it is possible to exclude from the image a majority of off-resonance components (mostly fat) present in the observed object, or to keep only off-resonance components (fat) without in-resonance component (water).
