Abstract

A cellular asynchronous code-division multiple access (A-CDMA) system operating in the 63-64-GHz band for short-range communications is analyzed. A simple propagation model for the 63-64-GHz band is first introduced and discussed. The system capacity, expressed as the maximum number of users per cell, is then analytically derived and favorably compared with other CDMA schemes operating in conventional frequency bands (i.e., below 2 GHz). Also, simple expressions for the system bit error rate (BER) are analytically derived for different cases and validated through computer simulations. Finally, power requirements are derived and the impact of atmospheric conditions is evaluated. It turns out that the use of the 63-64-GHz band significantly increases the capacity of A-CDMA, and proves to be suitable for cellular systems and personal communication networks (PCNs) provided that adequate power margins are taken into account in the design of the system
