Paper Abstract

This paper further examines a computationally simple scheme for estimating the symbol period in the presence of multipath that was recently proposed by Breinholt and Zoltowski. The algorithm is not premised on the symbol pulse shape making it robust to multipath effects. This paper relates simplifications that facilitate real-time implementation of the algorithm in a per sample update mode. The algorithm is presented in the context of the 8-VSB digital TV modulation standard but is equally applicable to other modulation formats. Simulations show that the algorithm performs well in the presence of multipath. Comparisons with a Gardner timing recovery loop show a reduction of jitter and faster frequency acquisition than that of the Gardner loop. The algorithm can be used alone or to speed the acquisition of other timing recovery methods. As an example, the algorithm is combined in a simple manner with a Gardner loop to provide significantly faster timing acquisition.
