Abstract: A multi-carrier transmission system, such as a DMT system. A receiver must be able to recover a sampling clock that is very accurately synchronized to a transmitter sampling clock. Typically, synchronization is achieved by using a reserved carrier, the pilot carrier, which is transmitted with a fixed phase. The receiver sampling clock is then phase locked to the pilot carrier. Frame timing can be recovered by using a correlation technique. Thus an improved method of recovering a sample clock and phase locking the sampling clock to a pilot carrier is provided.

Abstract: PCT No. PCT/SE97/01461 Sec. 371 Date Jun. 14, 1999 Sec. 102(e) Date Jun. 14, 1999 PCT Filed Sep. 1, 1997 PCT Pub. No. WO98/10556 PCT Pub. Date Mar. 12, 1998A multi-carrier transmission system, particularly a discrete multi-tone (DMT) system. Data is transmitted between two transceivers using a plurality of carriers. The frequency bandwidth of the system is divided between the plurality of carriers. The transmission system is adapted for operation in a heterogeneous network including a number of subscriber equipments having different channel characteristics and coexisting on the same cable. The length of cable for each subscriber terminal varies in relation to its respective location. The transmission system includes an allocation device for allocating the traffic of subscriber equipments having a shorter length of cable to tones starting from a higher frequency band of the system bandwidth.

Abstract: A multi-carrier transmission system such as a DMT based VDSL system. The system uses orthogonal carriers with high order QAM constellations for the transmission of multiple bits per carrier and symbol. This estimate includes digital receiver and transmitter units with the receiver unit including a symbol detection unit. This system is adapted to determine a parameter for each single carrier with the parameter being indicative of a deviation of a received signal from a corresponding constellation point. It compares the parameter with an upper lower limit and if the parameter is outside the limits, changes the constellation used to modulate the carrier to a neighboring constellation. The symbol detection unit may be used to determine a parameter such as the ratio d2/sigma2, where d is the shortest distance between neighboring constellations, sigma is a standard deviation and sigma2 is the variance of the deviations of the input and output signal values of the symbol detection unit.

Abstract: The invention relates to an optoelectronic component for converting electromagnetic radiation into an intensity-dependent photoelectric current. The component includes one substrate which is formed especially according to CMOS technology. The substrate has an integrated semiconductor structure and an optically active thin layer structure which is situated upstream in the direction of light incidence. The structure includes a layer of a transparent conductive material and at least one layer of semiconductor material, which are arranged on an isolating layer, inside which connection means are provided for establishing a connection between the optically active thin layer structure and the integrated semiconductor structure arranged on the substrate. The aim of the invention is to develop one such optoelectronic component in such a way that the electrical connection between the layer of transparent conductive material and an electrical potential connection can be established in a technically simple manner. To this end, the layer of transparent conductive material can be connected to the potential connection arranged outside the pixel arrangement by means of an additional conductive structure formed on the substrate.

Abstract: A multi-carrier transmission system. A received multi-carrier signal is sampled and digitized before FFT processing. Multi-carrier signals consist of many narrow band carrier waves which convey data via a wide band channel. The amplitude distribution of the sum of all the individual carriers is Gaussian. This means that high amplitudes occur with low probability. At the present time, analog to digital converters have a limited dynamic range. It is therefore normal practice to provide a compromise between cutting and quantization noise. The adverse affects of a course quantization have to be balanced between signal distortions caused by the loss of the low probability high amplitude signals.

Abstract: Control and/or observation of a plurality of devices, in particular consumer electronics devices, by a controller device with hypertext or hypermedia communication capabilities, such as a WAP-enabled mobile phone, preferably over a proximity bearer such as Bluetooth (RTM). Data can be sent from the controlled side to the controller side as well as from the controller side to the controlled side. Data flowing from the controlled side to the controller side may include data representing the operational status of the controlled device and/or data for programming the controller device to enable it to send control data to the controlled device for controlling the controlled device. The hypermedia data message generated by the controlled device may include hyperlinks or other menu options which may be dependent upon the current operational state of the controlled device, and which may be selected by the user of the controller, thereby causing the controller to send a control message to the controlled device.
