摘要： A method of power control in a wireless communication system, wherein blocks are transmitted from a transmitter to a receiver via a wireless transport channel. The method comprises comparing a target signal quality value with a received signal quality value and providing the results of the comparing step to the transmitter to adjust transmit power based on the comparing step. The target signal quality value is set by the following steps: determining an initial target value; detecting if a data block has been received; detecting if received blocks have been successfully decoded; and decreasing the target value when pass blocks are received and increasing the target value when failed blocks are received subject to monitoring a period of inactivity on the transport channel in which no blocks are received.

An estimate of an orthogonality factor can be generated based on said at least one channel coefficient. An estimate of the disturbance can be generated based on said at least one estimated channel coefficient. An estimate of input signal power can be generated using the received sequence. An estimate of cell geometry can be generated using the estimated orthogonality factor, estimated disturbance, and estimated input signal power.

摘要： The present invention relates to a method of fractionally spaced adaptive equalization which allows the achievement of the performances of the optimal linear receiver with a high degree of stability of the control algorithms. The technique is applicable to a generic communication system. The present method provides a fractionally spaced equalizer which is perfectly stable and has a good convergence rate without introducing any deterioration of the performances with respect to the optimal receiver and with an extremely low increase in the complexity of realization as compared to the prior art techniques. The invention is based upon the introduction of a whitening filter of the input signal to a fractionally spaced equalizer stabilized with the tap-leakage technique, where the whitening filter is a device able to make the power spectrum density of the signal--repeated with a period equal to the reciprocal of the signalling interval--constant.

摘要： Wireless receivers are described for receiving signals from a transmitter. A receiver can include a plurality of antennas each for receiving a version of a signal via a different propagation channel and providing that version to a respective input. Signal processing means can be included and configured to operate diversity processing of a supplied number of said inputs for use in performing detection of said signal. The receiver can include channel parameter estimation means, configured to estimate one or more channel parameters on the propagation channels. The receiver can also include selection means configured to select only a subset of said inputs to implement a specific dimensionality of the receiver diversity processing, in dependence on the one or more channel parameters indicative of channel conditions on said propagation channels. The diversity processing can be linear or non-linear. Related methods and software implementations and computer program products are also described.
