The receiver circuit for ultra-wideband integral pulse frequency modulated wireless sensor
The paper presents the novel receiver architecture for the short-range wireless sensor communication, based on Integral Pulse Frequency Modulator (IPFM) and Ultra-Wideband (UWB) pulse generator. UWB IPFM wireless sensor transmits ultra-wideband pulse pairs with information contained in the distance between consecutive pulse pairs. Multi-user coding is performed using delay elements, where each user has unique delay time. At the receiver input Low Noise Amplifier (LNA) amplifies UWB pulses and detect each pulse. Since the narrow pulses cannot be processed with digital signal processor, class C amplifier with integrated pulse stretcher is used at the output of the LNA. The amplified and stretched pulses are fed to the comparator which is followed by FPGA for digital signal processing and demodulation. The paper presents the architecture of the receiver that is implemented in discrete type laboratory prototype. Measurement results of the signals at each stage are presented for IPFM-based transmitter.
