Abstract
The signal-to-noise ratio (SNR) and signal-to-interference ratio (SIR) for multiuser time-hopping binary phase shift keying ultra-wide bandwidth impulse radio systems are jointly estimated using the moment-based method. Both additive white Gaussian noise channels and multipath fading channels are considered. Numerical results show that the new SNR and SIR estimators have normalized root-mean-squared errors of less than 0.2 in most cases considered.
