Blind channel estimation in OFDM-based amplify-and-forward two-way relay networks

Abstract

In this paper, we propose a blind channel estimation algorithm for amplify-and-forward two-way relay networks (AF-TWRN). The orthogonal frequency division multiplexing (OFDM) modulation is adopted for frequency selective channel. The channels are estimated in two steps. First the cascaded channel causing the self-interference is estimated using a proposed power reduction method. Then the other cascaded channel from source to destination is estimated by subspace method. Closed form formulas are derived and the numerical results are provided.
