Abstract

One of the basic keys in the next generation wireless communications systems is to propose a convenient channel estimation technique, which in turn provides a better Bit Error Rate (BER). In Multicarrier Code Division Multiple Access (MC-CDMA) system, channel estimation is very important to overcome the effect of channel fading, which may distort the symbols of the information and resulting in a considerable degradation in the BER. On the other hand, the digital modulator and demodulator associated with MC-CDMA modulation is an acceptable numerical complexity (logarithmic) for applications with low computing resources. In this paper, a New Channel Estimation (NCE) scheme has been proposed by reserving suitable positions for the pilot carrier, mainly based on interleaved partitions, by filling these carriers with the unit signal to avoid the computational complexity involved in the channel estimation scheme. The simulation results show that the NCE method applied to MC-CDMA system achieves a better improvement regarding BER performance under Rayleigh and Rice fading channels.
