Abstract

Maximizing system capacity is one of the major concerns in inband full-duplex (IFD) two-way relay (TWR) system using analog network coding (ANC). This paper compares 1-transmission-time-interval (TTI)-based ANC (1TA) TWR, in which each node operates in IFD mode, with 2-TTI-based ANC (2TA) TWR operating in inband half-duplex mode. System capacity of the 1TA TWR is derived with adverse factor such as direct link interference (DLI). Also, this work proposes an iterative optimal power allocation (OPA) method to maximize the system capacity, which is based on golden section search under total power constraint. Numerical results elucidate that the 1TA TWR based on the OPA outperforms the 2TA TWR in all cases of relay position and DLI.

Notes

  1. For simplicity and clearness, only one shared antenna for both transmission and reception is assumed since further analysis is straightforward in case of multiple shared antennas.

  2. It assumes that \(\tau\) may be controlled integer by integer, and the propagation delay difference between \(S_1\)–R and \(S_2\)–R links is ignored.

  3. Perfect cancellation is assumed in this work, so we consider exact channel state information (CSI) for each link. In reality, the CSIs are not able to be estimated perfectly although the CSI acquisition process was proposed in [7]. Thus, for further study the effect of the CSI error on the 1TA-ANC system should be analyzed with an aid of [16].

  4. The capacity of DR = 0.25 is identical to that of DR = 0.75 because of the deployment scenario.
