摘要： A system for processing an RF signal received via a plurality of antenna elements includes a connection arrangement (6) for selecting a sub-set of a given number of RF signals ( r i , r j ) received from the antenna elements as well as a processing arrangement (8) for combining the received RF signals of the selected subset ( r i , r j ) into a single RF signal for demodulation. The system includes a RF phasing circuit (18) for producing selective combinations of the received RF signals ( r i , r j ) by applying relative RF phase shift weights to the RF signals ( r i , r j ) 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 (14) generates for each said selective combination of RF signals at least one non-RF radio performance indicator (RPI) representative of the quality of the RF signals in the combination. A decision block (16) identifies the sub-set of received RF signals ( r i , r j ) to be selected as a function of the one radio performance indicator (RPI) generated for the selective combinations of said received RF signals ( r i , r j ). This arrangement facilitates the selection of the signals/antennas to be used for reception e.g. in a WLAN device by avoiding that the selection process may involve all the possible combinations.

The system includes: - at least one estimator (21, 22, 27; 24, 23, 25) for producing first and second channel estimates from the pilot signal and the data signals, and - a combination node (26) for combining the first and second channel estimates to obtain final combined channel estimates. The system includes an interpolator module (25) adapted for interpolating the second channel estimates over a basic estimation reference time (T) to produce equal numbers of channel estimates over the basic estimation reference time (T) derived from the data signal and the pilot signal respectively, and, possibly - rate adaptation modules (23, 27) adapted for mapping the channel estimates on the basic estimation reference time (T). The combination node is a summation node (26) producing the final combined channel estimates as a sum (26) of the first channel estimates and the interpolated second channel estimates.
