Multiple-access performance limits with time hopping and pulse position modulation
Fernando Ramirez-Mireles, R.A. Scholtz · 2002
The use of spread spectrum time hopping in combination with pulse position modulation for multiple access communications is studied. The multiple access performance is described in terms of the number of users supported by the system for a given bit error rate and bit transmission rate. Expressions for the maximum number of users and maximum transmission capacity in bits per second are found. Asymptotic values for these quantities are derived.
