Mobile radio systems with high power and bandwidth efficiency can be designed by the combination of code division multiple access (CDMA) and multi-carrier modulation. The problem of channel estimation in the downlink of a multi-carrier (MC)-CDMA system is investigated. We study pilot-symbol-aided channel estimation in two dimensions using two cascaded one-dimensional FIR filters, dimensioned as Wiener filters for the worst case channel conditions. The performance with real channel estimation is demonstrated for various mobile radio environments and velocities. Furthermore, we examine the accuracy of a simple approximation to evaluate the system performance with real channel estimation, where the analysis of the channel estimation is separated from the evaluation of the remaining mobile radio system
