Abstract: A method and system for archiving data. The data are classified according to their desired lifetime and then archived in a memory using a storage method whose reliability is in accordance with the desired lifetime. For example, when storing data in the cells of an EPROM, short-term data could be archived using larger programming voltage pulse increments than for long-term data, using a lower target threshold voltage than for long-term data, using wider programming voltage pulses than for long-term data, using higher starting programming voltages than for long-term data, using fewer programming voltage pulses than for long term data, using lower maximum programming voltages than for long term data, or using more levels per cell than for long-term data.

Abstract: A receiver section recovers the in-phase and quadrature components of a linear modulated data signal. The in-phase signal is sampled and quantized producing an in-phase sample stream, and the quadrature phase signal is sampled and quantized producing a quadrature sample stream. The in-phase sample stream and the quadrature sample stream are both over-sampled at a rate of N times a symbol rate of the data signal. A decimation section filters the quantized in-phase sample stream and the quantized quadrature sample stream to produce a reduced in-phase sample stream and a reduced quadrature sample stream at a rate of M times the symbol rate, wherein M is less than or equal to N.

Abstract: A transceiver and transmitter are shown. A baseband processor receives a signal for transmission. It converts the signal into amplitude and phase polar components. Each component is then processed—the phase component through a wideband phase modulator and the amplitude component through a wideband amplitude modulator, and the components are then recombined for further processing or transmission.

Abstract: The present invention relates to a communication system comprising a number of end user stations (hosts) connected over access networks and routing arrangements. The system supports a IPv6 (Internet Protocol version 6) addressing scheme, wherein the end user stations are connected to the routing arrangements over links, and sending of router advertisements from router arrangements to end user stations (hosts) being implemented to support provisioning of IPv6 addresses for the end user station. Router advertisements (RAs) from a routing arrangement to an end user station are sent with a controllable and variable frequency during an initial phase. During said initial phase, the frequency is higher at the beginning and lower at the end.

Abstract: Methods and apparatuses for iterative parameter estimation are described. The iterative parameter estimation includes performing a first estimation of a first portion of a signal to obtain first parameters of the portion of the signal, wherein the signal contains no known data symbols. The first portion of the signal is demodulated using the first parameters to recover data symbols. The demodulated first portion of the signal is checked to confirm correct demodulation of the first portion of the signal. A second estimation of the first portion of the signal is performed using the recovered data symbols to obtain second parameters of the first portion of the signal. Then, a second portion of the signal is demodulated using the second parameters when the first portion of the signal is correctly demodulated.

Abstract: A décor paper for use as a surface on a floor panel has applied to it quaternary ammonium compounds in a resin mixture. The resin may be urea or melamine resin, and the mixture may also include abrasion-resistant particles such as corundum. The mixture applied to the paper provides it with antistatic properties, so that, when used on a floor panel, very little static electricity is generated by people walking on it. The floor panel is made up by the paper, attached to a one surface of a carrier, with a corresponding paper attached to the opposing surface.
