The time dispersion, frequency dispersion, and spectral demand are major limiting factors in dealing with a higher data rate in mobile communication. The increase of customer demand and fluctuating the signal obtained on the mobile device because of multi-path fading becomes a significant challenge in recovering the transmitted signal. The Multicarrier Code Division Multiple Access (MC-CDMA) along with antenna diversity can reduce the fading effect considerably and provide high-speed data for future mobile communication systems. The use of Multi-Input and Multi-Output MC-CDMA mitigates the multipath effect of the transmission impairments caused by the frequency selective nature of the channel. However, successful implementation depends on proper Channel State Information. In this work, the Adaptive Pilot technique is proposed and incorporated, in which, the location and number of pilots in time and frequency domain are dynamically varied with the help of channel estimation itself thus increases spectrum utilization. This modification shows a clear improvement in performance and is observed through simulation. Further to enhance the performance, relaying technique is incorporated into the channel to reduce the Energy per Bits to the Spectral Noise Density (Eb/No), increase coverage area, reduce power requirements at mobile stations and will effectively reduce the number of base station.
