Abstract

Broadcast nature of the wireless channel enables wireless communications to make use of network coding at the physical layer (PNC) to improve the network capacity. Recently, narrowband and later broadband wireless analog network coding (ANC) were introduced as a simpler implementation of PNC. The coherent detection and self-information removal in ANC require accurate channel state information (CSI). In this paper, we present the bit error rate (BER) performance analysis with imperfect CSI for broadband ANC using orthogonal frequency division multiplexing (OFDM). The effect of time-selectivity is also studied to investigate its effect on the BER performance. It is shown that the fading tracking is an important problem for self-information removal.
