SNR and Carrier Phase Estimation of BPSK Signal
A method estimating signal-to-noise ratio (SNR) and carrier phase of the binary phase shift keying (BPSK) signal was proposed. First, the complex passband signal was converted to the complex baseband signal. T...

Recognition of Tone Signal Based on Eigenvalue Decomposition
A tone signal recognition method based on eigenvalue decomposition was proposed in order to distinguish the tone signal from the modulation signals. The recognition of a tone signal was transformed into the pr...

Improved Carrier Frequency Estimation Based on Autocorrelation
Two improved carrier frequency estimating methods were proposed. The original method estimates carrier frequency directly using the phase of the autocorrelation of the signal, while the improved methods constr...
