Has anyone done work in creating a stand-alone DSP hardware implementation of the outstanding dual-antenna diversity function in SDRuno with the RPSduo? The idea would be a digital DSP version of, say, the Timewave ANC-4 or QRM Eliminator device, that would input to an existing receiver or transceiver to provide for two-antenna noise cancellation, beam forming, and orthogonal fade reduction. A digital version would allow for easier and more precise operation. Most current stand-alone SDRs such as the Russian Malachite DSP2 already have the necessary components except for a second tuner and logic to control IQ phase/amplitude.
