A novel lossy-forward (LF) cooperative communication scheme based on the decode-and-forward (DF) protocol allowing source-relay link errors is proposed recently. The LF relaying scheme always allows the relay to forward the decoded information to the destination even though it may contain errors. The knowledge of the correlation between received information sequences is exploited in the decoding process at the destination to improve the system performance. In this paper, we derive exact expressions of the outage probability upper bound for a two-way LF relay system over Rician fading channels with random K-factor. The K-factor follows empirical distributions derived from measurement data. It is found that the two-way relaying with LF is superior to that with DF scheme in terms of the outage performance.
