A Timing Recovery Scheme Using an Adaptive Interpolator

A novel symbol timing recovery scheme using an adaptive interpolator is proposed in this paper. This scheme is based on interpolation filter and adaptive equalizer, with minimizing mean square error (MMSE) of output signal as its design rule, to guarantee optimum performance. This scheme cannot only eliminate the inter-symbol interference (ISI) but also compensate the symbol timing error. The simulation results show that its performance is better than the Lagrange interpolator or LMS equalization algorithm.
