Time-Compressed Synchronization Sequence for Future Spectrally Efficient Transmission Schemes

Abstract

In this paper, we propose a technique for generating a synchronization sequence for estimating time and frequency offsets for spectrum efficient transmission schemes. The synchronization sequence should have excellent auto-correlation characteristics without deteriorating the efficiency of various spectrum efficient transmission schemes. Since the columns of the discrete filter matrix obtained from the coefficients of the binomial function have a very short finite length and limit the band, the performance can be accurately estimated. In this paper, we propose a scheme for generating a sequence with excellent auto-correlation characteristics while being band-limited and, for example, verify the accuracy of the scheme.
