| 1. A receiver comprising:
a receive processing block to be coupled to a plurality of spatially separated antennas, the receive processing block comprising:
a delay block for each signal received by an antenna, wherein the delay of a particular delay block is determined according
to a geometric position of the antenna, to obtain a delayed signal corresponding to each signal;
a plurality of weighting components to apply weights to the delayed signals to produce delayed weighted signals; and
a plurality of combining elements to combine various ones of the delayed weighted signals to obtain combined signals, wherein
at least one combined signal is to be used for further receive processing.
