Overlay of cellular CDMA on AMPS forward and reverse link analysis

The forward and reverse link capacities of code division multiple access (CDMA) and analog cellular system in North America (AMPS) are derived when they are overlaid. Formulas that describe the relationship between the number of CDMA and AMPS users for a given carrier to interference ratio (C/I) of each are presented. A nonlinear system that reduces the power of narrow-band interference is introduced. Simulation results are presented for one narrow-band interferer.
