在本文中，我们描述了一种技术，将边信息到在基于GSM的系统的接收机的信道估计操作。该技术具有与标准方法相当的复杂性。仿真结果表明，在编码误码率（BER）方面，我们的技术产生约0.8 dB的增益在静态信道中，和1 dB的非色散瑞利和莱斯衰落信道。对于未编码的BER和检测到的错误的概率实现了类似的增益。这样的增益在蜂窝系统中是期望的。它们在链路裕量很高的卫星系统中是相当可观的。
In this paper, we describe a technique to incorporate side information into the channel estimation operation at the receiver in a GSM-based system. The technique has a complexity comparable to that of the standard method. Simulations indicate that in terms of coded bit error rate (BER), our technique produces gains of about 0.8 dB in a static channel, and 1 dB in non-dispersive Rayleigh and Rician fading channels. Similar gains are achieved for uncoded BER and probability of detected error. Such gains are desirable in a cellular system. They are considerable in a satellite system, where link margin is at a high premium.
