Abstract: Code Division Multiple Access (CDMA) is the technology used in all third generation cellular communications networks, and it is a promising candidate for the definition of fourth generation standards. The wireless mobile channel is typically frequency-selective causing interference among the users in one CDMA cell. In this work, CDMA Transceivers block has been studied widely, and an analysis of proposed model based on Orthogonal frequency-division multiplexing OFDM based Fourier transform on in Flat and Selective Fading Channels.
