Multi-user capabilities of UWBFM communications systems
This paper analyzes the multi-user capabilities of UWBFM communications systems. Multiple users operating at the same RF center frequency will be confronted with multiple-access interference that will ultimately limit the performance. Two particular cases are investigated: two users of different power and N users of equal power. Expressions are given for the receiver processing gain, the subcarrier SNR in the two-user case as well as the maximum number of equal power users and the capacity of the multi-user UWBFM communications system.
