Description
本出願は、2013年2月22日に出願された米国特許仮出願第61/768,004号に基づき、その優先権を主張するものであり、この仮出願の内容は、参照により本明細書に組み込まれる。
t(n)=p(n)/c 式(1)
ここで、cは光の速度を示す。
time=max(t(n))−t(n) 式(2)
リバースタイミング=(クライアント時間オフセットの最大値)−(クライアント時間オフセット) 式(3)
ここで、リバースタイミングは、0と各クライアントに関するクライアント時間オフセットの間の有効な数であり、また、時間オフセットの最大値は、最初にアンテナ素子121がある信号を受信してから、最後にアンテナ素子121がそれと同じ信号を受信するまでの時間の差分である。
