Abstract
This paper considers a channel state estimation (CSE) problem in a parametrized Hierarchical MAC (H-MAC) stage in Wireless Physical Layer Network Coding (WPNC) networks with Hierarchical Decode and Forward (HDF) relay strategy. The primary purpose is to present the results of a non-pilot based phase estimator performance evaluation. In particular, the performance comparison of a Matlab simulation and an over the air transmission using USRP N210 transceivers in terms of mean square error (MSE) and bit error rate (BER). Also, we analyze the properties of the Cramer Rao Lower Bound (CRLB) w.r.t. different channel parametrizations.
