Abstract

A hyper-resolution method has been used to estimate the wideband indoor channel impulse response at 1.3 GHz in a variety of environments within a building. The number of multipath components N and the Ricean k-factor have been investigated. The effect of the presence of people has also been monitored. The results show that if a 30 dB impulse response dynamic range threshold is considered. A value of N less than 7 is applicable to all cases for >90% of the time. It is also shown that the k-factor can be reliably estimated using only the three strongest components.
