ABSTRACT:
The present disclosure provides a method and apparatus of channel estimation for a wireless communication system. A pilot signal energy is estimated based on received pilot symbols. An estimated traffic signal energy of the traffic signal symbols is estimated based on the received traffic signal symbols, the received pilot symbols and a noise estimate. A traffic to pilot ratio is estimated based on the pilot signal energy and the traffic signal energy.
