摘要

天线阵列的使用有助于对抗无线蜂窝系统中的共信道干扰(CCI)。在干扰有限的情况下，基于确定性最小二乘(LS)方法的时空滤波技术可能与基于网格的算法相竞争，因为难以准确地模拟CCI的时空特征。我们考虑了在确定性时空均衡器输出处计算的编码位上的可靠性信息质量对接收机性能的影响。给出了采用线性滤波和决策反馈滤波技术的EGPRS接收机的仿真结果。

Performance of soft-output space-time equalization for EGPRS

The use of antenna arrays can help to combat cochannel interference (CCI) in wireless cellular systems. In interference-limited scenarios, spatio-temporal filtering techniques based on a deterministic least-square (LS) approach may be competitive with respect to trellis based algorithms, because of the difficulties of accurately modelling the space-time characteristics of CCI. We consider the impact on the receiver performance of the quality of the reliability information on the coded bits, computed at the output of the deterministic space-time equalizer. Simulation results are provided for an EGPRS receiver employing linear and decision-feedback training-based filtering techniques.
