Time-hopping SSMA techniques for impulse radio with an analog modulated data subcarrier

Abstract

There has been tremendous interest in wideband communications systems for personal and cellular communications. A time-hopping spread-spectrum communication system employing impulse signal technology has several features which may make it attractive for multiple access communication. These features are outlined and emerging design issues are described. Under ideal propagation conditions, multiple-access capability is estimated for such a communications system with analog frequency shift keyed modulations.
