Not Accessible

Your library or personal account may give you access

Abstract

We present a carrier phase and frequency estimator for 16-QAM with frequency acquisition range of ±0.5 times the symbol rate, speed of 15 times faster than differential frequency estimation, and robustness in tracking time-varying frequency.
