摘要： A method of maintaining a communication link between a network node and a mobile node of a communications network comprises providing at least two downlink transmission beams (A to D) and designating a first of the at least two beams as a primary transmission beam (e.g. B). The beams are used in accordance with a schedule. Received signal quality or signal strength measurements are taken at the mobile node and signaled to the network node. A quality of link on the primary transmission beam (e.g. B) and at least one other of the at least two transmission beams (e.g. A, C) is determined from the measurements signalled from the mobile node to the network node and the quality of link for the beams is compared to provide a comparison and the schedule varied in accordance with the comparison.

摘要： Described herein is a method of providing synchronization between a plurality of base stations (300) in a telecommunications system which comprises providing a random access channel in each cell (320). A local base station (300) uses the random access channel in the local cell to transmit a synchronization signal to neighboring base stations. For each base station, the time differences between received synchronization signals from neighboring base stations and the local synchronization signal are calculated. Each set of time differences is either used to autonomously synchronize the local base station or is centralized in a radio network controller and a set of corrections distributed from the RNC to the base stations.

摘要： Conventional Rake receivers for spread spectrum signals are typically restricted in the number of multipath components they can usefully combine. The present apparatus for combines all the useful multipatlh components in a received signal with modest complexity. Digital correlators are provided over the multipath delay spread of the signal at predetermined intervals and their outputs are maximal ratio combined. With close to rectangular transmission received filters, almost all the entire signal energy can be recovered at the output of the combiner even though no attempt is made to accurately to align any of the correlators onto a specific multipath component.

摘要： A wireless magnetic resonance imaging scanner has one or more local coils, a microwave antenna array, and a local oscillator, and an upconverter. The local oscillator signal from the local oscillator is transmitted from the microwave antenna array to illuminate the local coils. The local coils generate magnetic resonance signals at a first frequency and the magnetic resonance signals at the first frequency are upconverted in the upconverter to microwave frequencies. The local oscillator operates at a frequency within an unlicensed band, chosen such that desired sidebands for reception of the upconverted local coil magnetic resonance signals fall outside the unlicensed band.

摘要： In a method for improving signal extraction in a code division multiple access (CDMA) telecommunications system, a first iteration of interference cancellation is performed on the basis of bit rates for every signal which are the same as those in a previous frame of the same signal. Filtered and down-converted signals are demodulated in Rake receivers to provide output signals corresponding to decision variables and channel estimates. The decision variables are limited and remodulated and respread prior to the signals being reconstructed using the channel estimates. The reconstructed signals are summed, and each signal is subtracted from the sum to provide an ‘interference’ signal which is then used to obtain the individual signals. Each signal is then demodulated a second time in another Rake receiver to provide a tentative DPDCH signal, a TFI signal, a TPC signal and a SNI signal. The TFI signal is processed to provide a signal indicative of the bit rate which is used to both decode the DPDCH signal providing a data output and to provide an estimate of the bit rate for a subsequent frame of the same signal.
