Non-data-aided timing recovery scheme for MSK signals

This paper analyzes the signal decomposition expression for Minimum Shift Keying (MSK) signals. The Phase of MSK signal with real parts and imaginary parts is recovered from discrete-Fourier-transform of signal appropriate parts, and then Phase is translated into time. Based on this, a non-data-aided timing recovery is proposed for MSK signals by absolute algorithm. Compared with the existing algorithm, the proposed scheme is more superior in performance and is close to Modified Cramer-Rao Bound (MCRB).
