This unique feature draws much interest in smartphones, smart homes, intelligent vehicles, AR/VR, and IoT applications since accurate ranging/positioning adds a new dimension to existing wireless communication functions. The recently released IEEE 802.15.4z enhances UWB PHYs to increase the integrity and accuracy of ranging measurement and specifies a security extension for secure ranging [1]. Not many prior works have reported standard-compliant systemlevel UWB solutions except that some building blocks were discussed, such as coherent
