Physical layer network coding (PNC) technique has been adopted in recent works for increasing the system throughput in a two way relay channel (TWRC) where two users exchange their information via an intermediate node. In this paper, we investigate the effectiveness of increasing numbers of users for PNC technique where multiple pairs of users swap their information simultaneously through a single relay node for TWRC. This scheme uses interleave division multiple access (IDMA) for multiuser detection at the receiver. Moreover, a common chip level interleaver is shared for each pair of users instead of using a distinct chip level interleaver as in traditional IDMA. In addition, channel coding is integrated with the newly proposed scheme to achieve more reliable communications. The performance of the proposed system is investigated for the TWRC in terms of the bit error rate (BER).
