AB - In this paper, a new hybrid relaying protocol is investigated for the time division broadcasting protocol. Instead of simply performing amplified‐and‐forward or decode‐and‐forward on the received information of terminals, a well‐designed hybrid relaying protocol, in which network coding (i.e. the bit‐wise XOR) and superposition coding are chosen reasonably to combine the information of the terminals, is employed by the relay to forward the information of terminals. The approximate outage probability for the proposed protocol is derived in closed form, and the tightness of the expression is verified by Monte Carlo simulations. Meanwhile, the achievable diversity of the proposed protocol is analysed. Through both analytic and simulation results, we show that the proposed protocol can always achieve full diversity of two through reasonably selecting between the combining methods at the relay. The performance improvement of the proposed protocol is demonstrated through comparisons with several existing protocols in two different scenarios: (1) the transmitted power of the relay is less than the transmitted power of terminal and (2) the transmitted power of the relay is greater than or equal to the transmitted power of terminal. Finally, an optimal power allocation scheme at the relay is presented for the proposed protocol to minimise the outage probability. Copyright © 2013 John Wiley & Sons, Ltd.
