Abstract
In this paper, the requirement of symbol synchronization in MC-CDMA systems is investigated. Two data aided synchronization schemes are proposed which can be exploited both in downlink and uplink. In Scenario I, we spread the pilot data on some selected subcarriers and utilize the cyclic nature of pilot data in time domain for downlink synchronization and the correlation characteristic of spreading codes for uplink synchronization. In Scenario II, we allocate a longer PN code to each user which obtains a better cross correlation in time domain and apply a similar algorithm to Scenario I uplink case. Their performance are evaluated and compared in multipath fading channels.
