We investigate a simple protocol for multi-user synchronous high data rate communications between a central node and several terminals, in the case of a pulse based ultra wide band physical layer. Using RAKE combining with or without multiple antennas at either or both sides helps improve the signal to interference ratio (SIR) by typically 10 dB for 3 users in a LOS or NLOS channel. The protocol makes use of a simple iterative algorithm to maximize the SIR.
