Future army mobile multiple-access communications
Don J. Torrieri · 2002
Code-division multiple access (CDMA) is accepted as the basic means of providing mobile multiple-access communications in future Army wireless networks. However direct sequence CDMA is susceptible to the near-far problem. Although in principle the solution to the near-far problem is power control, this paper shows that fading severely limits what power control can achieve. Frequency-hopping CDMA networks largely avoid the near-far problem by continually changing user carrier frequencies over appropriate hopsets. Other inherent advantages of frequency hopping desirable in the next generation of Army wireless communication networks are described.
