METHOD AND APPARATUS FOR FREQUENCY OFFSET ESTIMATION |
摘要 |
Certain aspects of the present disclosure relate to a technique for estimating a frequency offset of a local oscillator using primary synchronization signal (PSS) and secondary synchronization signal (SSS) while initially acquiring a long term evolution (LTE) signal. In certain aspects, a frequency offset estimation procedure may include PSS-based frequency offset estimation and SSS-based frequency offset refinement. The PSS-based frequency offset estimation may include determining a suitable reference PSS and using the ascertained reference PSS to estimate a PSS-based frequency offset. The SSS-based frequency offset refinement may include determining a suitable reference SSS using the PSS based frequency offset and using the ascertained reference SSS to refine PSS-based frequency offset from the PSS-based frequency offset estimation.
