MMSE adaptive array antenna with sequential processing

摘要

High cost have been a big problem realizing the adaptive array antenna. Since an adaptive array antenna needs HF circuit for each element, circuit scale increase. In this paper, we propose a MMSE adaptive array antenna with sequential processing. When conventional MMSE criterion is used, SINR deteriorates for the decrement of correlation between elements. In order to improve degradation of SINE, a tapped delay line adaptive array antenna with sequential processing are proposed. The tapped delay line adaptive array antenna increase correlation using tapped delay line in a time domain, and it improves SINR. We show effectiveness of the proposal system through a theoretical study and a computer simulation.
