An improved energy detection receiver for toa estimate in mm-Wave system

It is challenging to acquire the first arriving path for the estimate of the time of arrival (TOA) in multipath channels, particularly for low signal to noise ratio. The energy detection (ED) receiver is a better scheme for TOA estimate in millimeter-wave (mm-Wave) ranging system since its simple circuit structure. However, the traditional algorithms for TOA estimate using ED cannot provide the adequate accuracy. In this paper, a novel ED receiver for mm-Wave TOA estimate is developed by employing the higher order cumulant technique. Results acquired in IEEE 802.15.3c models confirm the effectiveness and better performance of this solution.
