Parameter Estimation Method for Transform Domain Communication Signals

SHI Rong;DU Yu;HU Su;Science and Technology on Electronic Information Control Laboratory;National Key Lab of Communication,University of Electronic Science and Technology of China;  
Parameter estimation of transform domain communication signal is the precondition of its non-cooperated demodulation and information analysis.After a brief introduction to the transform domain communication signal model,its characteristic parameter set is described.The method and steps of parameter estimation are explained for basic parameters.Then the characteristics of cyclic code shift keying are utilized,and the segment number of a symbol on time domain is estimated through the differential processing between two adjacent symbols.In this way,the effect of reconnaissance transmission channels can be eliminated.It is the basis of demodulation and transmitted sequence acquisition.The validity and applicability of the above main methods are demonstrated by simulations.It provides an important reference for the reconnaissance and processing of new communication signals in the battlefield.
