CDMA Channel Model. CDMA (Code-Division Multiple Access) is the standard for 3G mobile communications. Like GSM, the multipath fading channel for CDMA was defined in [ 3 ] for different communication scenarios with different PDPs and Doppler spectra.The Forward CDMA channel is the cell-to-mobile direction of communication or the downlink path. It consists of: Pilot Channel is a reference channel which the mobile station uses for acquisition, timing and as a phase reference for coherent demodulation. It is transmitted at all times by each base station on each active CDMA frequency. Each .CDMA channels can be broadly categorized as Forward channel and Reverse channel. This chapter explains the functionalities of these channels. Forward Channel. The Forward channel is the direction of the communication or mobile-to-cell downlink path. It includes the following channels −. Pilot Channel − Pilot channel is a reference channel .
CDMA is a multiplexing technique used in wireless communication to transmit data, voice, and multimedia over cellular networks. Unlike its counterpart, GSM (Global System for Mobile Communications), which uses Time Division Multiple Access (TDMA), CDMA employs a unique method of channel allocation. Instead of dividing the . CDMA can support approximately \(120\) radio channels on the same physical channel. Another important feature is that the same \(120\) channels can be reused in adjacent cells, as the information bitstream of each user can still be extracted.cdma pptThese three different ways of providing access by multiple users to a cellular system are termed, respectively, frequency-division multiple access or FDMA; time-division multiple access (TDMA); and code-division multiple access (CDMA).cdma chanel for cell sector wireless communication cdma pptThese three different ways of providing access by multiple users to a cellular system are termed, respectively, frequency-division multiple access or FDMA; time-division multiple access (TDMA); and code-division multiple access (CDMA).Beginning with solid foundations in digital communications that are essential to unequivocal understanding of CDMA technology, this book guides readers through the fundamentals and characteristics of cellular CDMA communications.
This paper looks at the CDMA system and seeks for the appropriate way of enhancing the cellular capacity using cell sectoring, and shows that the reduction in interference brings about an increase in the number of users that access the network.Wireless Networking and Communications Group CDMA – Issues • So far, CDMA looks like a step backwards: ¾Tight synchronization is required to use orthogonal codes, which then break in a multipath channel anyway ¾Quasi-orthogonal codes cause self-interference, which dominates the performance in most CDMA systems
