(invited paper) abstract—code-division multiple-access (cdma) has flour- ished as a successful wireless networking technology in mobile cellular telephony, and gations of optical cdma (ocdma) strategies have addressed this supported in part by the defense advanced research projects agency (darpa. Performance analysis result and simulation result of mc-cdma using bpsk modulation ijedr1401053 international journal of engineering development and research ( wwwijedrorg) 312 figure 4 ber curve on rayleigh channel v conclusion in this paper we analyze that mc-cdma and cdma technologies. Multicarrier code division multiple access (mc–cdma) is a promising wireless communication technology with high spectral efficiency and system performance however, all multiple access techniques including mc–cdma were most likely to have multiple access interference (mai) so this paper mainly. Several system components for cdma such as gateway this paper proposes das using a code division multiple access (cdma) network that can operate with real-time function, bidirectional commu- nication, and unsolicited messages from remote private wireless data communication, a research project to de.
