- Abstract
- An efficient preamble structure for OFDM systems is proposed which inserts a short embedded repetition pattern (SERP) into conventional preamble structures allowing a two-step detection of the integer frequency offset (IFO). A coarse estimate of the IFO using the SERP is performed in the time domain prior to performing fine IFO detection in the frequency domain based on the original preamble structure. The complexity of the overall IFO detection procedure can be significantly reduced at a price of slight loss in SNR. (C) 2011 Elsevier B.V. All rights reserved.
