Abstract

Impulse radio (IR) is an ultra-wideband (UWB) time-hopping spread spectrum technique in which sub-nanosecond pulses are modulated to convey information by shifting the position of the pulses in the time axis. We investigate channel estimation for an IR UWB system with an antenna array receiver in multipath environments with multiuser interference. The estimation method is pilot symbol assisted and it is based on the maximum likelihood criterion.
