The performed procedure, joined to a convolution process, results in the complete estimation (i.e., amplitude, frequency and phase recovery) of any corrupted periodic signal. The aim of this work lies in its …

WebThese characteristics may involve received signal strength, angle of arrival, phase or the inherent noise in the wireless channels that degrades the signal-to-noise ratio [17,18,19,20]. Therefore, channel modeling is the key aspect to evaluating the possibilities of using the PLS methods for securing the information content between legitimate nodes. WebIt only requires information of the signalto-noise ratio (SNR) and signal-to-interference ratio (SIR) and is robust against variations of the interfering channel's power delay profile. Moreover, the results can be applied to time-varying channels by simply replacing the frequency correlation function by the time correlation function.
