Blind channel estimation in OFDM-based amplify-and-forward two-way relay networks
ICASSP 2016accepted
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 ca…
