Abstract

Frame synchronization is a key function in wireless communications systems that employ pilot-symbol-assisted modulation (PSAM). Compared to traditional frame synchronization problems, frame synchronization for PSAM is more difficult due to channel fading and receiver carrier frequency error. In this study an innovative scheme of frame synchronization is proposed for pilot-symbol-assisted modulation. The approach features decomposition of the problem into reduced problems by employing non-coherent detection technique. The applications of minimum mean squared error (MMSE) estimation to channel fading and maximum likelihood estimation to pilot sequence detection provide a vehicle for design optimization. Simulation shows the scheme has improved immunity-to receiver carrier frequency error than the only existing scheme in the public literature.
