Spread spectrum technology is currently a major contender for the next generation digital cellular mobile communications, wireless LANs and indoor communication system. The proposed project is to develop a new spread spectrum communications technology conceived by the project co-ordinator and his research students. Preliminary studies indicated that capacity higher than the conventional code sequence assignment technique can be achieved using the same frequency bandwidth. The main advantage of the technology is that implementation can be much simpler than conventional spread spectrum systems. The project will develop a number of prototypes and evaluate their performances experimentally. By the end of this project, we expect to be able to demonstrate the viability of this technology and verify experimentally the predicted capacity gain under different operating conditions.
