Software-defined radio [sdr] systems, i.e. systems wherein components typically implemented in hardware

Official title: {Software-defined radio [SDR] systems, i.e. systems wherein components typically implemented in hardware, e.g. filters or modulators/demodulators, are implented using software, e.g. by involving an AD or DA conversion stage such that at least part of the signal processing is performed in the digital domain (digital baseband systems H04L25/00; digital modulation/demodulation H04L27/00; CDMA H04B1/707; TDMA H04B7/2643; image transmission H04N5/00)}

H04B1/0003 (Software-defined radio [sdr] systems, i.e. systems wherein components typically implemented in hardware) appears on 1,861 US grants and 1,855 published applications in this corpus.
