Analysis of the Narrowband Interference Effect on Multi-carrier Systems Timing Synchronization

ZHAO Fu-cai,HU Yi-hua,HAO Shi-qi,YAN Fei (Electronic Engineering Institute of PLA,Hefei,Anhui 230037,China)  
In multi-carrier systems,the most popular of the pilot-aided timing estimators is the one proposed by Schmidl and Cox(SC),which only one training symbol is used for symbol timing recovery and carrier frequency acquisition.Generally,the proper action of the timing estimator may be strongly affected by the presence of disturbances,like narrowband interference(NBI)signals.This paper investigates the effect of NBI signals,on the timing synchronization for multi-carrier systems.The performance of the SC symbol timing synchronizer is evaluated in an analytical way in the presence of narrowband interferers.Also,the probabilities of both missing and false detection of a training sequence are addressed.
