Abstract: A radio receiver, configured to use an impulse UWB, includes: a reception antenna which receives the impulse UWB, a reception unit which amplifies the received impulse UWB and detects an envelope of the impulse UWB, maximum-peak and minimum-peak detection units which detect a maximum value and minimum value of the envelope, respectively, a comparator which acquires signal data from the envelope with an initial threshold value, a baseband unit which measures an error rate of the signal data, an MPU which calculates a correction value based on the error rate, and an arithmetic unit which calculates a corrected threshold value based on the maximum, minimum and correction values. The arithmetic unit transmits the corrected threshold value to the comparator. The comparator acquires the signal data from the envelope based on the corrected threshold value transmitted from the arithmetic unit.

Abstract: The systems and methods described herein are directed to techniques for improving battery life performance of end devices in resource monitoring systems which transmit data using low-power, wide area network (LPWAN) technologies. Further, the techniques include providing sensor interfaces in the end devices configured to communicate with multiple types of metrology sensors. Additionally, the systems and methods include techniques for reducing the size of a concentrator of a gateway device which receives resource measurement data from end devices. The reduced size of the concentrator results in smaller, more compact gateway devices that consume less energy and reduce heat dissipation experienced in gateway devices. The concentrator may comply with modular interface standards, and include two radios configured for transmitting 1-watt signals. Lastly, the systems and methods include techniques for fully redundant radio architecture within a gateway device, allowing for maximum range and minimizing downtime due to transmission overlap.

Abstract: A method that incorporates teachings of the subject disclosure may include, for example, analyzing a signal to identify a present interference and extracting the interference from the signal. The extracting can include comparing a presence time for the interference with a reference time; if the presence time exceeds the reference time and at least one of a plurality of filters is available for filtering the present interference, an available filter of the plurality of filters is activated, thereby causing filtering of the interference from the signal. If no filter is available due to activation of the filters for filtering a plurality of previously identified interferences, a priority order is determined for the present interference and the previously identified interferences, based on their interference signal levels. The filters are assigned to the interferences in accordance with the priority order. Other embodiments are disclosed.
