具有干扰消除的GMSK接收器
摘要：
一种具有干扰消除的GMSK接收器，包括：线性均衡器(309)，被配置为耦接到来自第一天线的接收到的信号，并且提供第一软比特；自适应估计器，例如自适应MLSE(315)，耦接到第一软比特，并且被配置为提供第二软比特；质量评估器，耦接到第一软比特，并且被配置为提供质量指示；以及，切换功能(325)，耦接到线性均衡器和自适应MLSE，并且根据质量指示来控制以提供对应于第一软比特和第二软比特的至少一个的输出软比特(331)。GMSK接收器可以被扩展到多个天线，并且讨论了用于在GMSK信号中的干扰消除的对应方法。
摘要（英）：

A GMSK receiver with interference cancellation includes a linear equalizer (309) configured to be coupled to a received signal from a first antenna and to provide first soft bits, an adaptive estimator, e.g., adaptive MLSE (315) coupled to the first soft bits and configured to provide second soft bits; a quality assessor coupled to the first soft bits and configured to provide a quality indication; and a switching function (325) coupled to the linear equalizer and the adaptive MLSE and controlled in accordance with the quality indication to provide output soft bits (331) corresponding to at least one of the first soft bits and the second soft bits. The GMSK receiver can be extended to multiple antennas and corresponding methods for interference cancellation in a GMSK signal are discussed.
