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: The mobile terminal speed of movement method has a channel estimate (30) estimating fading. Autocorrelation is carried out to obtain a first value (33) for different speeds of movement. The first value is compared with different reference levels (34) and an estimate (36) made of the speed of movement.

Abstract: Method of decoding an incident UWB signal including successive incident pulses respectively received during successive Pulse Repetition Periods, each incident pulse including one transmitted symbol among M possible symbols, said transmitted symbol being corrupted by Inter Symbol Interferences (ISI), said method comprising the steps of: determining a correlation matrix (“), whose terms respectively represent the correlation between all the M possible symbols transmitted in a current Pulse Repetition Period, and at least in the previous and in the next Pulse Repetition Periods; performing a correlation between an incident current pulse received during a current PRP and the M possible symbols transmitted in said current PRP and at least in the previous and in the next PRPs for obtaining a correlation vector (Y); preprocessing said correlation vector (Y) including reducing the effect of the ISI from said correlation vector (Y) by using said correlation matrix (“); decoding said preprocessed correlation vector (Y") for obtaining the bits of the transmitted symbol included in said incident received current pulse.

Abstract: A method and device for handling write access conflicts in interleaving, in particular for high-throughput turbo decoding for wireless communication systems; the device comprises N interleaving buffers (CLk) that are respectively connected to N producers (PRk), an LLR distributor means and N single port target memories (TMk). At any time step, each interleaving buffer receives m LLR inputs from the producers and has to write up to M of these into a register bank (RBk), which comprises W registers. M denotes the maximum number of concurrent write operations supported per time step and W denotes the maximum buffer size. M and W are design parameters and are chosen for the standard case and not for the worst case. m-M producers have to be stalled whenever m is larger than M and m producers have to be stalled whenever a buffer overflow occurs (more than W LLR values). Finally, at any time step one LLR value is fetched from the register bank and written to the SRAM interleaving memory.

Abstract: This method for carrying out the flexible demodulation of data modulated following an amplitude modulation in quadrature is used in a communications system employing a code division multiple access technique (CDMA) and an optical frequency division multiplexing (OFDM) using non-binary spread codes. The invention includes steps for determining a simplified expression specific to the logarithm of the likelihood ratio.

Abstract: The transmission power control method has the transmission power adjusted as a function of the power information received. The transmitter has two power amplifiers (PA1,PA2) which are individually selectable together covering the total power plane. Each amplifier covers a different power zone, and is selected as a function of transmission efficiency. There is a transmission interrupt criteria, after which the amplifiers are reset.

Abstract: The invention relates to a method for producing image sensors on the basis of TFA technology including of an amorphous thin-layer system that has been applied on a crystalline ASIC. The inventive method enables the production of image sensors on the basis of TFA technology, which improve the picture quality at low luminous intensity by reducing the dark currents. The photodiodes in the thin-layer material that are configured as pixels are linked with transistor structures in the crystalline ASIC via back electrodes. The transistor structures have particularly low leakage currents due to implantation technology or optimization of the production process.
