Co-channel interference is a dominant limiting factor for LTE uplink system capacity. BS (Base station) MMSE-IRC (Minimum mean square error — interference rejection combining) receiver, as a promising approach for spatial domain interference handling, is introduced in LTE-Advanced Release 13. This paper firstly gives the signal model and receiver structure for BS MMSE-IRC. To evaluate MMSE-IRC performance...
Various technologies in LTE/LTE-Advanced have significantly improved the data throughput of 4G systems. However, the coverage of LTE networks, a very important performance metric to operators, receives relatively less attention. In this article we describe the motivations of LTE coverage enhancements from several aspects. Through link budget analysis, the limiting link and channels are identified...
