Abstract

A variable data rate CDMA system is tested for mobile and personal multimedia random access satellite communications. The system utilizes a constant occupied bandwidth, and has variable data rates and processing gains to mitigate communication link impairments and to provide variable data rates on demand. A conceptual hardware system is developed which uses MSK-type constant envelope direct sequence spread spectrum modulation and handles data rates from 4-64 kbps with FEC. The receiver structure provides variable data rates on demand during a call without the aid of system control earth stations. Both the IF loop back and satellite link test performances of the prototype equipment prove it is suitable personal and mobile satellite applications.
