UWB signal reception in a ranging system can be accomplished by either coherent receiver or non-coherent receiver. Correlation receiver is a type of coherent receiver while energy detection (ED) receiver falls into the non-coherent category. In this paper, we evaluate their ranging performances using the channel profiles measured in various indoor environments. The effects of important system parameters such as sampling rate and threshold on the ranging performance are also investigated. Results show that ranging accuracy is heavily dependent on the system parameters settings, especially in LOS environment. The correlation receiver requires much higher sampling rate to achieve the same ranging accuracy as compared to ED receiver. The study also shows that regardless of receiver type used, the resultant ranging error for NLOS environments can be described by a unified model. The proposed model is validated by measurement data.
