摘要： A computing system for gathering media status information and other information about contacts in a user's contact list includes a server, a user device, and one or more contacts (or contact devices). The user device communicates with the server and requests media status information regarding the contacts. Media status information may include information about the media content currently (or most recently) accessed by the contacts. The server receives the request from the user device, collects the information and sends it to the user device. The server may else send connection information to the user device. The user device receives the information and displays it to the user. The user device may include a message service such that messages can be sent to and received from the contacts. Also, the user may request particular media content accessed by the contacts.

摘要： Method and apparatus for improving data transmission in a digital subscriber line (DSL) system. The transmitter (100) determines whether a spectrum of an inverse Fourier transform (IFT) (102) is periodic with respect to a clock of a predetermined standard-size IFT and communicates this information to the receiver. Based on this information, the receiver adapts the FT if desired. In effect, the receiver adapts its signal processing algorithms to process the received signal in accordance with the transmitter's IFT size. In this manner, transmission performance is improved.

摘要： The object of the invention is a method and an arrangement for separating signals operating in the same channel. In the solution according to the invention, the signals to be transmitted are conditioned so that the receiver at the other end of the transmission route is able to separate an effective signal from an interference signal. The invention can be applied in the TDMA systems used in data communication cellular networks.

摘要： A time-division multiplex communication transmission apparatus includes a logic processing circuit, a digital filter, a modulation circuit, and a high-frequency amplification unit. The logic processing circuit performs logic processing of input burst data and outputs a burst timing signal for each time slot for time-division transmission. The digital filter converts output data from the logic processing circuit into baseband data for modulation. The digital filter is reset at a time slot boundary when no burst data signal is present in an adjacent time slot. The modulation circuit modulates an output signal from the digital filter. The high-frequency amplification unit performs burst waveform processing of an output signal from the modulation circuit on the basis of a burst timing signal from the logic processing circuit.

摘要： An apparatus for avoiding spectrum spreading in switching on and off a transmitter in a station included in a time multiplexed radio transmission system, e.g. a mobile telephony system, where two mutually 90-degree phase-shifted baseband signals (sin a(t), cos a(t)) are generated, each of these signals being intended to modulate a carrier wave. The apparatus includes means (MP, DAP, DAI, DAQ) achieving that the power of the baseband signals follows an increasing reference level at the start of each time slot and follows a decreasing reference level at the end of each time slot.
