In this paper, we consider a general bi-directional relay network with twosources and N relays when neither the source nodes nor the relays know thechannel state information (CSI). A joint relay selection and analog networkcoding using differential modulation (RS-ANC-DM) is proposed. In the proposedscheme, the two sources employ differential modulations and transmit thedifferential modulated symbols to all relays at the same time. The signalsreceived at the relay is a superposition of two transmitted symbols, which wecall the analog network coded symbols. Then a single relay which has minimumsum SER is selected out of N relays to forward the ANC signals to both sources.To facilitate the selection process, in this paper we also propose a simplesub-optimal Min-Max criterion for relay selection, where a single relay whichminimizes the maximum SER of two source nodes is selected. Simulation resultsshow that the proposed Min-Max selection has almost the same performance as theoptimal selection, but is much simpler. The performance of the proposedRS-ANC-DM scheme is analyzed, and a simple asymptotic SER expression isderived. The analytical results are verified through simulations.
