摘要： Systems and methods are described for providing a throughput of 10 Gbps or more in a coaxial cable network and which operate at high frequencies above the existing services on home coax in the range 2 GHz to 10 GHz, or more. The network uses a wide signal bandwidth, in the range, for example, of 8 GHz. Operating above the CATV band and satellite services, the network coexists with these services without mutual interference. The system could be used in networking systems, such as MoCA 3 and Access systems. This is achieved by using a splitter with a low loss and low isolation in the 2-10 GHz range at the point-of entry (POE) of the network signal. Alternatively, an active node to provide a signal booster or a repeater function at the point-of-entry (POE) can be used.

摘要： The invention relates to a method and a device for operation of two wireless services whereas a first service is broadcasting signals within burst with known time distances between the bursts and a second service is transmitting signals at least between a first partner and a second partner. The problem to be solved by the invention is to enable a user to use applications of at least to services concurrently at the same time with the same device. The problem is solved by an operation of one and the same device which is receiving bursts in a first mode of the first service and is switched from the first mode into a mode of the second service during the time between the bursts of the service.

摘要： An efficient algorithm is described for use with OFDM receivers that characterizes the impulse response of a communication channel using frequency domain techniques that reduce computational and memory requirements, relative to time-domain cross-correlation methods, without sacrificing algorithm performance. An FFT engine is used to transform a time domain input sequence, the transformed sequence is multiplied by the conjugate of the expected sequence, the product of several sequences is averaged, then the FFT engine transforms the average back to a time domain sequence, the magnitude of which is the impulse response of the channel.

摘要： The invention relates to a method for creating an interpolated image between a previous image and a current image in a video stream. The invention also relates to an image processing system for creating an interpolated image between a previous image and a current image in a video stream. The invention is based on the following principle: a motion estimator generates at least two vector fields, one at a temporal position smaller then 1A, and another at a temporal position greater than 1A. Then occlusion detection is done to detect covering and uncovering areas. A first vector is fetched from the first vector field and a second vector is fetched from the second vector field. If there is covering, the up-conversion vector is the second vector; if there is uncovering, the up-conversion vector is the first vector; if there is no uncovering-covering, the up-conversion may be either the first vector or the second vector. In this way, the up-conversion vector points at the correct original segment values in the previous image and the current image.
