Low-Complexity Diversity Reception

摘要

A system may comprise a plurality of signal processing paths, a bin-wise combiner, an inverse transformation block, and a DAC. Each signal processing path may comprise a transformation block that is operable to transform a first time-domain digital signal to an associated frequency-domain signal having a plurality of subband signals. The bin-wise combiner may be operable to combine corresponding subband signals of the plurality of signal processing paths. The inverse transformation block may be operable to transform output of the bin-wise combiner to an second time-domain signal. The DAC may be operable to converts the second time-domain signal to a corresponding analog signal.

1. A method comprising:
performing by circuitry of an electronic receiver:
receiving a first signal via a first antenna of said electronic receiver;transforming said first signal into a plurality of subbands comprising at least a first subband and a second subband;receiving a second signal via a second antenna of said electronic receiver;transforming said second signal into a plurality of subbands comprising at least said first subband and a second subband;cophasing and combining said first subband of said first signal and said first subband of said second signal to generate a first subband of a combined signal; andcophasing and combining said second subband of said first signal and said second subband of said second signal to generate a second subband of a combined signal.
