1. Introduction
Wireless communication systems are experiencing massive growth in terms of traffic and devices volumes currently. However, the capacity limitations confine many potential user demands and application perspectives. In fact, the interference plays a crucial role in current wireless systems which induces a typical upper bound to the system performance. To mitigate the mutual interference caused by parallel transmission to different users/antennas, many interference cancellation (IC) methods have been proposed in the literature [1]. They can be classified into two main types, i.e., pre-IC at the transmitter side and post-IC at the receiver side. Considering the uplink/downlink duality [2,3], without loss of generality, we focus on the downlink scenario, i.e., transmitter side processing techniques, in this paper. Transmitter side processing strategies can be generally divided into two categories, i.e., linear pre-equalization and non-linear precoding. Due to the effect of noise enhancement, linear methods have a poor power efficiency. Alternatively, this disadvantage can be overcome by non-linear precoding strategy, e.g. Tomlinson– Harashima precoding (THP) [4,5]. In contrast to its dual to decision-feedback equalization (DFE) at the receiver, THP avoids error propagation since the transmitter have the exact knowledge of data signals to be sent. Moreover, THP can be considered as the one-dimension approximation of dirty paper coding (DPC) [6,7], which is the most practical candidate to achieve the capacity promised by DPC [8] with feasible computational complexity. It has been demonstrated that the processing order has a great impact on the system performance [9]. The order plays a key role in the sense of maximizing the signal-to-noise ratio (SNR) of the subchannels [10] or in the sense of minimizing the error-variance between the data signal and the received signal [11]. A large volume of works exists on permuting the processing order of the users according to the channel matrix H in the literature. Briefly, these sorting methods can be classified into three categories according to their reordering criteria: column norms of H, column norms of H1 and diagonal entries of HHH, which typically correspond to SQRD [12], V-BLAST [13] and Cholesky decomposition [11], respectively. Moreover, lattice reduction [14] aided THP is able to improve the system performance further.
