Abstract :
The performance of direct-sequence spread-spectrum (DS/SS) in packet radio networks suffers from the near-far problem. This can be mitigated by the use of multiuser receivers. This paper introduces a model for peer to peer communications using a simple parallel interference cancellation (PIC) technique, which requires cancellation of only a few dominant interferers. The system performance is evaluated for various spatial arrangements of users, and for different loading conditions. Simulation results are provided for PIC
