Design of 6.7-7.9 GHz UWB indoor localization RF receiver

The paper gave a novel and realizable scheme of nocoherent digital-analog mixed receiver detection according to Ultra wideband indoor positioning receiver system analyzed the realization and performance of the RF circuit, meanwhile, provided the simulation results. Compared with other schemes, the scheme adopts the controllable integral detection circuit as the A/D conversion section , which realized the ideal-combination of RF circuit and digital baseband circuit and also solve the problem that UWB signal needs a high sampling rate in addition to detection of the received signal. As the same time, it proved that the integral detection circuit had benign performance through the test of the designed material object.
