Abstract
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. Then baseband signal vectors were rotated step by step from 0 to 2π, and the maximum and minimal values of the power on the real axis were found so that the SNR value could be estimated. The rotated phase according to the maximum value was the estimation of the carrier phase. Simulation results show that the method can get satisfied estimation precision by using small number of symbols.
