On performance of time-hoping impulse radio system with space time coding

Impulse radio (IR) is a promising candidate for short-range, high data rate multiple-access wireless communications. In a multiuser scenario, there are pulses collisions between the signal of the desire user and the interfering users, which degrade the system performance. In this paper, space-time block coding (STBC) is employed in the IR system to exploit space-time diversity for improving performance. Several types of receivers are also proposed and their performances are studied.
