Abstract :
This paper clarifies an estimation method for the carrier offset frequency of an orthogonal coding multi-carrier CDMA system under multi-path fading. It analyzes inter channel interference and inner channel interference which are caused by the multi-carrier offset frequency. An estimation method for the carrier offset frequency adopts a prediction method. Prediction coefficients are obtained by the Burg algorithm of a maximum entropy method. As a result of simulation, it is shown that the bit error rate (BER) is 3.5×10-3 at 15 dB of Eb/N0 for a 32 kbit/sec data rate and 16 subchannels of the orthogonal coding multi-carrier CDMA in multi-path fading
