Implementation of GSM channel estimation using open-source SDR environment

Channel estimation and equalization is a major area of research and development in communications engineering. However in the open literature there is no elaborate report on how to implement it on real signals from base-stations. In this paper we give the detailed steps to implement channel estimation block on real GSM signals using open-source software defined radio (SDR) environment. This work is expected to help all the researchers trying to implement and test channel equalization algorithms on real signal.
