Patent EP-0666661-A2 (EP)
Inventor: ZUMKELLER MARKUS GRUNDIG E M V
IPC: H04L27/00

Abstract: It is known that the new digital broadcasting which is to be introduced will be transmitted throughout Europe in different, very broad transmission frequency bands. However, since the transmission characteristics of the transmission channel and the system characteristics of the transmitter and receiver change according to the transmission frequency, different transmission modes adapted to the latter have been defined. In order to identify a transmission mode of this type on the basis of synchronisation errors in the receiver, without transmitting control data and without loss of data, the transmission duration of the zero symbol is evaluated according to the invention. If a transmission mode has been identified on the basis of the transmission duration of the zero symbol, reception parameters of the receiver which are important for reception are automatically set. Alternatively, the number or the frequency spacing between the carrier frequencies can be evaluated in order to identify the transmission mode. The method according to the invention can be used in all frame-oriented transmission methods with different transmission modes.

Abstract: A convolutional interleaver and addressing scheme are provided. Up to B consecutive symbols containing errors can be interleaved such that they are separated from each other by at least N intervening symbols. Memory, such as RAM, is configured to provide (B-1) cells of increasing size for storing symbols from a data stream. A first one of the cells (CELL 1) has M storage locations adapted to store M symbols. Each successive one of the cells (CELL 2; CELL 3) has M more storage locations than the immediately preceding cell for storing M more symbols than the immediately preceding cell, where        M=N/B          . The cells are successively addressed to write a next symbol from the stream into a next write symbol location in a currently addressed cell and to read a symbol from the location of the currently addressed cell immediately following the next write symbol location. The locations are accessed in a first revolving manner such that the last location in a cell is followed by the first location in that cell. The cells are addressed in a second revolving manner such that the (B-1)th cell is followed by the first cell, or vice versa. An intervening transfer stage can be provided within the RAM between the (B-1)th cell and the first cell to directly transfer the next symbol to the interleaver output. Each consecutive symbol from the stream is written into a next consecutive one of the cells. A deinterleaver is provided having the same structure.

IPC: H03M13/00
Filed: 1996-07-12
Abstract: Adaptive cut-off criteria are determined during iterative decoding of multi-dimensional coded information to be transmitted. The relative entropy or approximations to the relative entropy are used to change the weighting of the decisions of consecutive partial iteration steps. If the partial iteration steps do not cause a change in the relative entropy above a predetermined threshold level, the iterative decoding is interrupted. The information to be decoded is transmitted in multiple frames, and a threshold is determined for each frame.

Abstract: A method for determining the contour of a diffuse surface, including the location of the workpiece (12) on a reference plane (14). A computer (16) is employed to generate a virtual grating of fringe patterns that vary pixel gray scale values sinusoidally in a horizontal image row. The gray scale variation is repeated for all image rows, and said values are supplied to a video projector (18) which projects the values onto the diffuse surface of the workpiece (12) at an angle relative thereto. The diffuse surface and gray scale values are viewed with a video camera (20), which camera acquires and provides electronic images of the diffuse surface and values without the use of a camera grating. The viewing is performed at an angle different from the angle at which the fringe pattern is projected onto the diffuse surface. The video camera then supplies signals to the computer that represent the electronic images acquired by the camera, and the computer is employed to process the signals in a manner that determines the contour of the diffuse surface.

Abstract: A heater mechanism for a crystal pulling apparatus is disclosed. Electrodes made of copper or the like and disposed under a heater are connected to the heater via graphite members. A cover member is attached to each graphite member, so that the downwardly extending portion of the cover member surrounds the outer surface of the graphite member. Accordingly, a leak or splash of a melt is prevented from contacting the electrodes. The length of each graphite member is equal to or greater than the distance between the bottom surface of the heater and the top surface of a melt spill tray which distance is measured when the heater mechanism is raised. The cover member is vertically slidable along the outer surface of each graphite member. Thus, even when a material melt leaks out from a crucible, the electrodes of the heater mechanism can be protected from a fusion damage or the like which would be otherwise caused by the leak of the melt.

Abstract: The present invention is a method and device for synchronization at OFDM-systems. A signal is read into the synchronization block in the time domain, i.e. before fourier transforming of the signal via the FFT-processor, according to Figure 1. In the synchronization block the frame clock for start and input of data in the FFT-processor is regained. For OFDM-reception it is very important that this input starts at the right point of time to make possible detection of data. The point of time for the input to the FFT-processor is therefore adjusted in relation to the regained frame clock. 
     When the frame clock has been regained the frequency error can be estimated, which is also performed in the synchronization block. The frequency error is utilized in a control loop for feed back to an oscillator which generates a complex rotating vector which is multiplied by the input signal for compensation of the frequency error. The invention can be utilized at OFDM-system with guard space or OFDM-system with pulse forming.
