Abstract

Example embodiments presented herein are directed towards a system, and corresponding method, for interference suppression of wireless communication signals. The method may comprise embedding a differential phase tracking signal (e.g., a zero amplitude differential phase tracking signal) in a transmitted wireless communication signal. Thereafter, a differential phase may be measured between the embedded transmitted wireless communication signal and a wireless reference signal. This differential phase measurement may be utilized in the suppression of interference in the wireless communication signal.
