Abstract

Burst synchronization scheme for a millimeter band OFDM uplink system is proposed. For the estimation of subscribers access and its frequency offset and time offset, an OFDM-CDMA pilot signal is adopted. The accuracy and probability of error estimation are investigated by the theoretical analysis and simulations. This paper clarified that the proposed synchronization scheme has the capacity of four users simultaneous access with 10% of error estimation probability, when 64 of the subchannels are used for spreading each subscribers pilot signal
