Abstract :
The use of spread-time CDMA for ultrawideband (UWB) wireless communication is proposed and its capability for supporting many high data rate users is investigated. Furthermore we study an hybrid technique, namely, spread-time/time-hopping to increase the capacity of the abovementioned technique and simultaneously minimize the near-far effect in a typical CDMA system.
