Abstract
Described in this document are ways to accomplish high resolution and high dynamic range Doppler-Effect measurements for use in wireless communications and other applications such as positioning. Doppler Effect (interchangeably called Doppler shift or Doppler frequency shift) measurements have traditionally been done with purpose-built devices, such as pulse-based radars. Presented in this document are alternative ways to incorporate Doppler frequency shift measurement using modulated carrier signals with a conventional radio, without additional hardware.
