N2 - In this paper, we develop a simple blind channel estimation algorithm for two-way relay network (TWRN) that consists of two terminal nodes and one relay node. We consider the frequency selective channels and adopt the orthogonal frequency-division multiplexing (OFDM) modulation to compensate the inter-symbol interference (ISI). By applying a non-redundant linear precoding at both terminals, we propose an algorithm that is effective of estimating two cascaded channels and is consistent with the two-phase two-way transmission protocols. The method to remove the inherent ambiguity of the blind channel estimation is discussed. Finally, the numerical results are provided to corroborate the proposed studies.
