Time frequency analysis of a noisy carrier signal
Rosser, Daniel Mark
MetadataShow full item record
Digital communication signals are inherently nonstationary (time varying spectral content) signals due to their information content. This suggests the use of time frequency analysis methods for detecting these signals as well as obtaining the desired signal parameters. For signals employing phase- shift-keying (PSK) to convey information, the important signal parameters are the carrier (sinusoid) center frequency and information (bit) rate.
