H04B1/0021 - CPC Classification

Classification description:

Details of transmission systems, not covered by a single one of groups - ; Details of transmission systems not characterised by the medium used for transmission; 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 wherein the AD/DA conversion occurs at radiofrequency or intermediate frequency stage Decimation, i.e. data rate reduction techniques
