A Wideband Multicarrier CDMA Cellular Communications System.

Abstract

The demand for mobile access to high data rate communications services such as video teleconferencing, internet access, or file transfer continues to grow rapidly for a wide variety of military as well as commercial applications. Existing mobile narrowband cellular communications systems do not have sufficient bandwidth to support high data rate applications. Simply increasing the bandwidth of existing cellular systems to support higher data rates results in a significant degradation in signal quality and reliability due to frequency-selective fading. The wideband cellular system design presented in this thesis features a multicarrier approach that minimizes frequency-selective fading effects for very high data rate applications and a dual mode reverse channel that facilitates efficient utilization of bandwidth for low to very high data rate applications.
