Abstract:
1. A code division multiple access (CDMA) receiver comprising: a first antenna configured to receive first signals; a second antenna configured to receive second signals; a first sampler configured to sample the first received signals at twice a chip rate and output the first received signal as a first data stream; a second sampler configured to sample the second received signals at twice a chip rate and output the second received signal as a second data stream; a first serial-to-parallel (S/P) converter configured to split the first data stream into a first odd data stream and a first even data stream; a second S/P converter configured to split the second data stream into a second odd data stream and a second even data stream; a first multipath combiner configured to combine a multipath of the first odd data stream to generate a first multipath combined odd signal stream; a second multipath combiner configured to combine a multipath of the first even data stream to generate a first multipath combined even signal stream; a third multipath combiner configured to combine a multipath of the second odd data stream to generate a second multipath combined odd signal stream; a fourth multipath combiner configured to combine a multipath of the second even data stream to generate a second multipath combined even signal stream; a first over-sample combiner configured to combine a first multipath combined odd signal stream and the first multipath combined even signal stream to produce a first combined sample data stream; a second over-sample combiner configured to combine the second multipath combined odd signal stream and the second multipath combined even signal stream to produce a second combined sample data stream; and an antenna diversity combiner configured to combine the first combined sample data stream and the second combined sample data stream to produce a combined output.
