Study on multiple antenna combining for sequentially switched antenna array receivers

The traffic from many smartphones in a bullet train is increasing and there is a fear of the capacity lack in the train-unit entrance circuit. In the Sequentially Switched Antenna Array Receiver, the array antenna elements fix the receiving point against the travel of the bullet train. In addition, it is necessary to synchronize the switching with the sampling period. We propose a multiple antenna combining scheme that satisfies the requirements for the sequentially switching, and show its effectiveness by computer simulations using experimental data.
