- This paper validates the concept of receiving LTE MIMO signal to obtain spatial multiplexing gain with single radio beam switching antenna system that consists of a single active antenna with multiple parasitic elements around it. Performance measurements were conducted by using a testbed equipped with single radio. Test results with LTE signal have not been reported so far. Measured SNR of the recovered LTE signal was 31.33 dB on average in indoor environment. From the implementation perspective, the transient time during the beam switching results in performance degradation. It is beneficial to reduce the time as short as possible by using fast switching device. Considering that transient time is fixed once a switching device is hardwired, it is good to reduce the switching rate as possible because low switching rate corresponds to the reduced occurrence of transient state.
