Time reversal technique for multi-user wireless communication with single tap receiver

In this paper we propose a TR-MISO space-time multiplexing scheme for multi-user wireless communication with single tap receivers. Analytical investigation is carried out to derive a frame work for designing the system. With the space-time multiplexing scheme the interference that exists in a normal time reversal multi-user system can be further mitigated. With 6 simultaneous users using the proposed scheme an enhancement in the average SIR of each user from 8 dB to 22 dB is feasible. Measurement data are then used to verify the analytical results and a good agreement is observed.
