    摘要: A base station signal is applied to antenna elements. One signal from a first element is electrically modified and evaluated in conjunction with a second, unmodified signal from a second element. The modified signal is further modified and again evaluated with the unmodified signal. The results of the two evaluations are compared to determine a relative phase and/or amplitude at the respective elements.
