Performance of an LTE femtocell base station employing uplink antenna selection

This paper presents experimental evaluation results from a practical LTE-FDD femtocell base-station employing uplink antenna switching. The effects of different antenna training and channel variation rates are analysed under realistic propagation conditions. Significant performance gains in terms of average receiver SINR and error rates are observed for the antenna selection receiver, especially at low mobile terminal speeds typical of indoor femtocell applications. These results demonstrate the effectiveness of simple low-cost antenna selection techniques in practical indoor cellular systems.
