Abstract

We propose a new training sequence and integer frequency offset estimation algorithm using the characteristics of chirp training signals. We also propose modifications of known fractional frequency offset estimation algorithm and timing synchronization algorithm. The training sequence is composed of one up and two down chirp symbols, also known as Newman phases. The integer frequency offset estimation algorithm uses the effect of timing and frequency offsets on the matched filter outputs of the chirp signals. Autocorrelation and reversed autocorrelation are used to acquire the timing instant and the fractional frequency offset. We present the whole timing and frequency synchronization procedure and its performance via Monte Carlo simulations in multipath channels. Our procedure shows better performances compared to previously published algorithms.
