Effect of channel estimation error on performance of physical layer network coding
Keyvan Yasami, Ali Abedi · 2011
This paper investigates the effect of channel estimation error on performance of physical layer network coding, in which the relay maps the superimposed noisy modulated data received from the two end terminals, to network coded combination of the source packets. Knowledge of channel coefficients is required for network code selection at the relaying terminal. We consider physical layer network coding with optimum code design and evaluate network throughput in presence of channel estimation error.
