Abstract: The wireless communications system comprises: a plurality of remote units, wherein each remote unit is configured to convert a respective RF signal into a plurality of time and frequency samples, perform a noise estimation corresponding to the plurality of time and frequency samples, compute a plurality of coefficients corresponding to the plurality of time and frequency samples that have an amplitude greater than at least a predefined threshold value, and multiply each of the plurality of coefficients by its corresponding time and frequency sample to create a plurality of weighted time and frequency samples; at least an intelligent switching unit, coupled to the plurality of remote units, wherein the intelligent switching unit is configured to receive the plurality of weighted time and frequency samples from each of the plurality of remote units, temporally align the pluralities of weighted time and frequency samples, compute a set of weighted sums of time and frequency samples and transmit the set of weight

Abstract: A stress monitoring method includes the steps of acquiring a plurality of individual readings of at least one physiologic data parameter over a period of time, storing the plurality of individual readings, determining the average of at least a portion of the plurality of individual readings, and comparing at least one individual reading to the average to identify any differences between the average and the at least one individual reading.
