This paper investigates the reason why the predistorted signal is sampled and feeds back to an adaptation block as reference for digital predistorter (DPD) to be updated in real-time (RT) by comparing a non-real-time (NRT) method with off-time processing. In addition, by deriving a simple algorithm based on gradient descent algorithm with minimum square error criterion, the steady-state condition...
DRM (Digital Rights Management) and CAS (Conditional Access System) techniques have been used to cut off the illegal use of contents. These techniques, however, brought about much inconvenience as restricting the move or play of the contents of even legal users. In this paper, we propose a new technique for sharing DRM contents based on domain according to the increment of the demand about the pliant...
It is well known that the proper ordering is crucial for overall performance in OSIC method. However, when the layers or streams are modulated differently such as multi-user MIMO case, exact ordering is not possible. It is called different modulation effect which causes the performance degradation. In this paper, we propose the novel detection method which can eliminate the different modulation effect...
