Principles of Communication Systems Simulation with Wireless Applications

Chapter 18. Two Example Simulations

We conclude our study of simulation techniques and methodology by presenting two very different examples. The first example is a simulation of a CDMA system operating in a multipath/fading environment. Thermal noise and interference are also included in the simulation model. A number of performance results can be generated by the simulation model. These include the bit error rate (BER) as a function of the thermal noise level (P_E versus E_b/N₀), BER as a function of the spreading factor (spread-spectrum processing gain), and BER as a function of the number of interfering signals. Even though the system presented here is more complex than those presented in previous chapters, a number of simplifications are made ...
