Abstract: Motion detection using channel impulse response signals and related systems, methods, and apparatuses are disclosed. An apparatus includes an analog input terminal of a receiver processing circuitry, an analog to digital converter (ADC) circuitry, and a processor. The analog input terminal receives a reflected predetermined pattern signal provided by a receiver antenna. The ADC circuitry samples the reflected predetermined pattern signal received by the analog input terminal to generate reflected predetermined pattern samples. The processor determines an average of magnitudes of a sum of collections of the reflected predetermined pattern samples and determines whether a moving object is sensed responsive to the determined average and a predetermined threshold value.

Abstract: Motion detection apparatuses are disclosed. The motion detection may be performed using one or more of a sub-window of a predetermined time window, a predetermined threshold value that is settable responsive to changes in one or more environmental factors, or a detection trigger. An apparatus includes a processor and an analog-to-digital converter (ADC) circuitry to sample a reflected predetermined pattern signal to generate reflected predetermined pattern samples. The processor captures collections of the reflected predetermined pattern samples corresponding to a predetermined time window and determines a sum of the collections or sub-collections. The processor determines an average of magnitudes of the determined sum and determines that a moving object is detected responsive to a predetermined threshold value.
