    A software simulation testbed for CDMA wireless communication systems
    (1999) Sundaramurthy, Vishwas; Cavallaro, Joseph R.
    This thesis develops a software wireless communication testbed which simulates a Code Division Multiple Access (CDMA) link. CDMA is a popular technology in cellular systems due to its superior capacity and performance. The designer of CDMA systems has a wide array of signal processing algorithms to choose from and a variety of operating environments to deal with. The testbed is a tool to evaluate these design options and trade-offs in different scenarios. The backbone of this system is a wireless CDMA multiuser link built using Simulink and Matlab. An efficient method of system modeling is used to speed up the simulations. This testbed can be used to study the performance of a CDMA wireless link with variation in system parameters and channel conditions. The use of Real-Time Workshop for DSP code generation is studied. This method is useful for rapid prototyping of algorithms and in DSP-based simulation acceleration of the testbed.

    A Software Simulation Testbed for Third Generation CDMA Wireless Systems
    (1999-10-20) Sundaramurthy, Vishwas; Cavallaro, Joseph R.; Center for Multimedia Communications (http://cmc.rice.edu/)
    This paper describes a testbed which simulates a third generation Code Division Multiple Access (CDMA) wireless link. The designer of next generation wideband CDMA systems has the choice of a wide array of advanced signal processing algorithms and a variety of operating environments. The Rice testbed is a tool to evaluate these design options and trade-offs in different system scenarios. The backbone of this testbed is a wireless CDMA multiuser link built using Simulink and Matlab. An efficient method of system modeling is used to accelerate the simulations. The testbed also uses a method for rapid prototyping of algorithms and DSP-based simulation acceleration for new algorithm complexity and performance evaluation.
