A fast simulation technique for performance testing of the RF/IF chain of CDMA receivers

We propose an improved approach to the simulation of the CDMA forward link. The simulator achieves its computational efficiency by adopting a simplified CDMA system model without compromising much of its practicality. Additional reduction in the computational complexity is obtained by implementing bit level operations for certain receiver tasks. Improved processing algorithms are also introduced, which further facilitates the simulation process. The rationale behind the development of the simulator as well as many techniques involved could prove beneficial to a CDMA receiver designer in terms of shortening the design cycle and reducing the computational power requirements.
