In this paper we introduce an adaptive hybrid decision algorithm for video or image scaling. The algorithm combines a simple interpolation method with a more cost intensive one. With this approach it is possible to maintain the quality level of the high level interpolation while remarkably saving cost.
Within the scope of the research project presented in this paper an alternative architecture to mixing based receivers like hetero- or homodyne receivers is investigated: the sixport receiver. The theoretical aspects of the system concept are shown and the structure of the analog front-end is presented supported by measurement results. The analog front-end is based on a microwave circuit with a carrier...
The six-port receiver concept offers new possibilities on the way towards a multimode low cost receiver frontend for highest frequencies. The expense for the reduced effort on analog side is a higher complexity in digital signal processing. After a comparison between conventional and six-port receiver technology this paper offers a solution to implement a complete communication link including frequency,...
