Abstract
Systems and methods are disclosed herein to provide improved clock synchronization between wireless data communication transmitters and receivers, including Orthogonal Frequency Division Multiplexing (OFDM) communication systems. In accordance with one or more embodiments, a clock synchronization system is disclosed that includes an adaptive threshold function operative in conjunction with a synchronizer that adjusts the frequency and phase of a receive clock oscillator. Such a synchronization system may offer improved capabilities such as resistance to radio frequency (RF) channel impairments and noise, rejection of mis-decoded clock synchronization signals, and handling of multiple transmitters.
