摘要： A method of transmitting signals from a base station towards user terminals in a cellular communication system. The method includes generating diversity signals, wherein at least one of the diversity signals is subjected to a selectively variable RF phase shift. Specifically, a set of radio link quality indicators is determined at the base station, wherein each radio link quality indicator is representative of the quality of the radio link between the base station and a respective one of the user terminals. The set of radio link quality indicators is used to generate an aggregated radio quality indicator, which in turn is used to selectively vary the variable RF phase shift. For example, the phase shift may be selected, which optimizes the aggregated radio quality indicator.

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.
