摘要:
A portable radio receiver and a method of operating the radio receiver during Standby Mode is provided. The method comprises deactivating at least part of a receive path of a receiver until the start of a data-detection time interval in a frame in the event that estimated values of predetermined characteristics of a signal received by the receiver during the frame are within corresponding thresholds. The predetermined characteristics are affected by pre-conditioning functions performed on the receiver prior to the start of the data-detection time interval.

A battery-powered portable radio receiver and a method of operating the battery-powered radio receiver during Standby Mode in order to decrease battery-current drain is provided. In Standby Mode, a receive path of the radio receiver is activated during a data-detection time interval for the detection of data destined for selected receivers, and a preconditioning time interval for performing pre-conditioning functions with respect to the receiver before the data-detection time interval. The method includes: (a) activating the receive path at a predetermined time instant before the start of the data-detection time interval to perform the pro-conditioning functions with respect to the receiver, (b) detecting a predetermined characteristic of the received signal affected by each of the pre-conditioning functions; (c) comparing each of the predetermined characteristics with e threshold; (d) where the predetermined characteristics are within their respective thresholds, deactivating the receive path until the start of the data-detection time interval, and then reactivating the receive path fur the data-detection time interval; and (e) where the predetermined characteristics are outside their respective thresholds, continuing the pre-conditioning functions until the predetermined characteristics are within their respective thresholds, then deactivating the receive path until the start of the data-detection time interval, and then reactivating the receive path for the data-detection time interval.

Linear transformations are carried out on a matrix that represents information such as an image or a communication. In an aspect, the matrix is processed to remove duplicate information. The duplicate information can be duplicate rows, or zero rows. This matrix is then transformed into a modified matrix, indicating duplicate information is removed to produce a modified matrix.

In a receiver having at least two fingers, the fingers tracking at least one path of a multipath channel, a method includes the steps of forming a finger block of at least two of the two fingers and jointly tracking the fingers of said finger block. The step of jointly tracking includes the steps of generating direction metrics of each of a set of possible directions of joint movement of the fingers of the finger block, selecting one of the direction metrics according to a predetermined criterion, and moving the fingers of the finger block in the directions indicated by the selected direction metric.
摘要:
The present invention is a channel estimator based on the values of received data and on a priori probabilities only of received symbols. The channel estimator includes a symbol probability generator, a noise variance estimator and a channel tap estimator. The symbol probability generator generates a priori probabilities only of transmitted symbols found in the received signal(s). The noise variance estimator estimates at least one noise variance corrupting the received signal(s). The channel tap estimator generates channel estimates from the received signal(s), the a priori probabilities and the noise variance(s).
