ABSTRACT:
A method for processing signals is disclosed and may include performing using one or more circuits, orthogonally multiplexing, on to a single processing chain, a plurality of replicas of a signal received via a corresponding plurality of spatially distinct antennas. The orthogonally multiplexed plurality of replicas of the received signal may be converted to corresponding digital multiplexed signals that include multiplexed replicas of the plurality of received signals. The corresponding digital multiplexed signals may be demultiplexed to generate the plurality of replicas of the signal received via the corresponding plurality of spatially distinct antennas. The plurality of replicas of the received signal may be spread, for example, may be orthogonally spread.
