Abstract :
Two candidates for high-capacity cellular systems are simulated and analyzed, one code-division multiple access (CDMA) and one time-division multiple access (TDMA) system. Simulations of the CDMA example indicate a high sensitivity to variations in certain system parameters. The TDMA example is a GSM system using random frequency hopping and operating without frequency planning. The simulations show that the TDMA system has at least the same capacity as the CDMA candidate. Soft capacity, efficient use of voice activity, and diversity are features available in both systems
