    摘要： A method and a channel estimator are provided for providing channel estimates for a wireless communication system. The method comprises generating a first vector of channel coefficients having certain values. To the first vector is applied a regularization algorithm operative to generate a second vector, which comprises regularized channel coefficients having certain values, by regularizing the values of the channel coefficients of the first vector such that the difference between the values of consecutive regularized channel coefficients of the second vector is less than the difference between the values of consecutive channel coefficients of the first vector.

    摘要： A monitored delay set in a telecommunications system is filtered by, for each delay value in the monitored delay set, adjusting a corresponding quality indicator to indicate a lower quality if the delay value is not also represented in a newly obtained set of delay values. For each delay value in the monitored delay set, the corresponding quality indicator is adjusted to indicate a higher quality if the delay value is also represented in the newly obtained set of delay values. For each of the quality indicators, if the quality indicator is less than a first threshold value, the corresponding delay value is then removed from the monitored delay set.

    摘要： A method for generating a filtered signal quality value used in a power control system of a wireless communication apparatus. An estimated signal quality value of a received signal is generated. A filtered signal quality value is generated based on the estimated signal quality value. The filtered signal quality value is generated in dependence of at least one of registering a difference between a first and a second reference signal quality value, and a change in transmitted power of said received signal. A power control device (20) comprising a signal quality estimator (23), a BLER estimator (22), a regulator (24), and an inner loop (25) is configured to implement the method.
