摘要： A system for processing an RF signal received via a plurality of antenna elements includes a connection arrangement for selecting a sub-set of a given number of RF signals received from the antenna elements as well as a processing arrangement for combining the received RF signals of the selected sub-set into a single RF signal for demodulation. The system includes an RF phasing circuit for producing selective combinations of the received RF signals by applying relative RF phase shift weights to the RF signals that are combined; each combination includes RF signals received from a number of adjacent antenna elements equal to the number of the RF signals in the sub-set to be selected. A radio performance estimator generates for each selective combination of RF signals at least one non-RF radio performance indicator representative of the quality of the RF signals in the combination. A decision block identifies the sub-set of received RF signals to be selected as a function of the one radio performance indicator generated for the selective combinations of the received RF signals.

摘要： A system for estimating the transfer function of a transmission channel such as the downlink channel in a CDMA system over which a pilot signal and a data signal are transmitted. The system includes at least one estimator for producing first and second channel estimates from the pilot signal and the data signals and a combination node for combining the first and second channel estimates to obtain final combined channel estimates. The system includes an interpolator module adapted for interpolating the second channel estimates over a basic estimation reference time to produce equal numbers of channel estimates over the basic estimation reference time derived from the data signal and the pilot signal respectively, and possibly rate adaptation modules adapted for mapping the channel estimates on the basic estimation reference time. The combination node is a summation node producing the final combined channel estimates as a sum of the first channel estimates and the interpolated second channel estimates.
