A coarse cell search scheme of TD-SCDMA systems

This paper presents a novel initial cell search (frame synchronization) scheme of TD-SCDMA system. This algorithm uses the implicit power transition in the special frame structure and introduces a different power ratio detector comparing with the conventional non-coherent algorithms, which makes it less complicated and more reliable. We verify our algorithm by computer simulations, and the results show a good and robust performance in a wide range of signal-to-noise ratios (SNRs).
