Abstract
Recently, many blind and non-blind methods that equalize the channel in the time domain to remove Inter Block Interference (IBI) don’t consider the presence of the Carrier Frequency Offset (CFO) or assume that the CFO is estimated perfectly. In this paper we consider an Multi-Carrier Code Division Multi Access (MC-CDMA) system with presence of CFO and we develop a semi blind approach to jointly estimated the CFO and the Time domain Equalizer (TEQ) based on the zero and non-zero pilots inserted in the transmitted symbol, in addition to reduce the complexity of our derived algorithms we adopted an adaptive standard Least Minimum Square (LMS) algorithm related to the proposed batch algorithms. The simulations results obtained demonstrated the effectiveness of our algorithms when compared with the blind once.
