Performance Analysis of a Cdma Wireless Local Loop Systems
In this paper, the capacity of the Code Division Multiple Access Wireless Local Loop (CDMA WLL) system is analytically derived, and the capacity gain achieved in a CDMA WLL over a cellular mobile environment is calculated. The results show that the CDMA WLL system can support up to 36 % more users than CDMA cellular mobile system. The paper also propose a new approach to increase the reverse li...
متن کاملPerformance Evaluation of Rake and Pre-Rake Receiver for a Wireless DS- CDMA System
A new method to deal with multi path fading environment for DS–CDMA wireless networks has been proposed. Here, depending upon the statistical nature of the channel, signal is transmitted as a sum of various spreaded signals; each one delayed and scaled according to the delay & strengths of the multi paths of the transmitted channel. New method known as Pre-Raking is performed at the transmitted...
متن کاملPerformance Enhancement of Mc-ds/cdma System Using Chaotic Spreading Sequence
A novel chaotic spreading sequences for multi-carrier direct sequence code division multiple access (MCDS/CDMA) system is proposed. With this spreading sequence in the MC-DS/CDMA system, the effect of multiple access interference can be mitigated by choosing the spreading sequences with appropriate crosscorrelation properties. The performance of the system is assayed in the multiuser environmen...
متن کاملPerformance enhancement of a multicarrier DS/CDMA system through interference cancellation
In this paper, successive interference canceller (SIC) is adopted for the performance enhancement of a multicarrier DS/CDMA system and its performance is analyzed in a Rayleigh fading channel. A successive interference canceller is employed for each subcarrier of a multicarrier DSlCDMA system and the outputs of SICs are combined through the maximal-ratio or equal-gain combining. Numerical resul...
متن کاملCapacity of broadband CDMA wireless local loop systems
Wireless Local Loop (WLL) is an emerging technology that allows rapid connection to the wired network from remote locations. A crucial issue for WLL is the system design so that the number of subscribers can be maximized while providing the required quality of service. In this paper, we consider a broadband wireless local loop with fixed point users and we evaluate the subscriber capacity for a...
