Network capacity for bidirectional communication between pairs of wireless end users assisted by a relay terminal can be improved by network coding at the physical layer PNC . Narrowband analog network coding ANC was introduced as a simpler implementation of PNC in a flat . frequency-nonselective fading channel. Recently broadband ANC has been studied for communication over a frequency-selective fading channel. In ANC the end user removes its own information from the received signal before detecting the data of the other user. Clearly the network performance of ANC scheme depends on the selfinformation removal at the destination terminal. In this paper we discuss the impact of imperfect self-information removal on the performance of broadband ANC in terms of the bit error rate BER and achievable throughput in a frequency-selective fading channel. The theoretical minimum mean square error MMSE equalization weight for ANC based on single carrier with frequency domain equalization SC-FDE radio access is derived by taking into account the self-interference. We have used analysis and computer simulation to .
