Abstract
It is meaningful to investigate MC-CDMA systems without Cyclic Prefix (CP) because of its spectral efficiency. This paper extend a superimposed periodic scheme for channel estimation to the equivalent representation for MC-CDMA systems without CP over the FIR channel, a simple first order statistics is used. Considering multi-user cases and the affect of non-zero means, an iteration method is proposed to improve the estimation performance and no extra power is lost. The simulation results demonstrate its effectiveness.
