Abstract
This paper proposes a hardware configuration using only single pole dual th row (SPDT) switches to realize the previously proposed automatic calibratio n method using transmitting Signals (ACT) for the adaptive array in TDD com munication systems. The proposed configuration obtains the same calibration values as the conventional ACT does while reducing the number of switch br anches. The transmission pattern using the proposed calibration method is a lso presented based on an experimental adaptive array testbed in an actual microcell environment. The experimental results show that the ideal radiati on pattern formation is achieved by employing the proposed calibration meth od in an environment with a moving terminal station and where arriving co-c hannel interference exists.
