Adaptive Joint Estimation of Symbol Timing and Carrier Frequency Offset for OFDM Systems

Abstract—Synchronization is an important issue in orthogonal frequency-division multiplexing (OFDM) systems including symbol timing and carrier frequency offset (CFO) estimation. In this paper, we derive a new subspace based CFO estimation method exploiting the Cyclic Prefix (CP) samples which are not disturbed by the preceding OFDM symbol. As a special and more practicable case, we provide an adaptive joint symbol timing and CFO estimation scheme. It is robust in both AWGN channel and frequency selective channel.
