Superanalysis of Optimum Combining with Application to Femtocell Networks

A femtocell technology - towards the deployment of small-cell networks - is a key enabler for improving indoor coverage and throughput per network area at a low cost in future wireless networks. However, these small-cell networking inevitably increases cochannel interference due to aggressive (even uncontrolled) reuse of spectral resources. One of the attractive approaches to alleviating the cochannel interference is a multiple-antenna technique for which accurately characterizing the effects of interference is crucial but challenging. To elucidate this important problem, the authors analyze the performance of interference rejection diversity combining, often called the optimum combining, in an uplink two-tier femtocell network.
