TL;DR: In this article, the authors proposed sampling frequency offset estimation schemes using various mixture of consecutive symbols in DVB-T (2K) channel model, which showed that the proposed schemes can improve the performance of the estimation by decreasing the noise effect within consecutive symbols.

Abstract: In an OFDM system, the sampling frequency offset between the transmitter and receiver is known to cause the inter-channel interference (ICI), resulting in performance degradation. Sampling frequency offset can be generally estimated by correlation of the pilot signal within contiguous OFDM symbol. In this paper, we propose sampling frequency offset estimation schemes using various mixture of consecutive symbols. We conduct a simulation in DVB-T(2K mode) system, which shows that the proposed schemes can improve the performance of sampling frequency offset estimation by decreasing noise effect within consecutive symbols in AWGN channel model.

TL;DR: The authors present a fast, open-loop, all-digital frequency offset estimation technique, whose performance is assessed in two different communication scenarios: a TDMA satellite link employing standard modulation and burst formats, and a mobile cellular terrestrial radio system with signal and channel characteristics obeying the pan-European Group Special Mobile (GSM) recommendations.

A Frequency and Timing Period Acquisition Technique for OFDM Systems
Hiroshi Nogami,Toshiro Nagashima +1 more
TL;DR: In this article, a frequency and timing period acquisition technique for orthogonal frequency division multiplexing (OFDM) systems is presented. Butler et al. introduced a pseudo-noise (PN) sequence to assign these frequencies of the pilot symbol so that the acquisition range can be widened for both additive white Gaussian noise (AWGN) and multipath fading channels.
