Many reasons cause multi- carrier CDMA to be the best technology in the latest mobile generations known by fourth generation for


mobile. As well known, the greatest enemy for any wireless communication is multi- path fading which usually result in distortion in


time- domain, or in frequency domain or even in both. Therefore any new technique applied into mobile communication system is


concerning with mitigating multi-path fading distortion which appears in form of reducing BER level. In this paper three techniques


have been combined in order to enhance mobile system performance in the presence of multipath fading channel. These techniques


are, orthogonal frequency division multiplexing (OFDM), code division multiple access (CDMA), and modified space shift keying


(SSK). The last technique is considered special case for MIMO technology. By the aid of MATLAB code, proposes system was


simulated in order to display BER performance versus variation in the SNR at many various system conditions.
