Title:
METHOD OF DETECTING FREQUENCY OFFSET IN OFDM WIRELESS COMMUNICATION SYSTEM AND THE DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2003/055115
Kind Code:
A1
Abstract:
The invention proposes a method and a device thereof for detecting the frequency offset value, i.e. frequency offset, in a wireless communication system which is based on the OFDM (Orthogonal Frequency Division Multiplexing) technology. The said method have the characteristic of obtaining the correlation peaks by calculating the cross correlation between the incoming signal and the reference signal; and then, calculating the frequency offset with several correlation peaks. The inventive device is advantageous with respect to the simple circuit implementation and high interfere-proof ability.
