Systems and methods for measuring wireless signal quality

Abstract

Systems and methods are provided for calculating a SINR measurement for an oversampled P25 C4FM wireless signal received by P25 user equipment or a P25 receiver to determine whether a P25 network and the P25 user equipment or the P25 receiver have been successfully deployed. Some methods can include calculating a first order envelop mean value for the oversampled wireless signal, calculating a second order envelop mean value for the oversampled wireless signal, calculating a fourth order envelop mean value for the oversampled wireless signal, using the fourth order envelop mean value and the second order envelop mean value to estimate the SINR measurement, and using the first order envelop mean value and the second order envelop mean value to refine the SINR measurement.
