Description
Tmin=nwin 2/BW
として決定されてよく、
BWは最大の可能な帯域幅である。
x=sqrt(Ptx)*sin(2*pi*fc*t)
としてMathlab(登録商標)構文で決定されてよく、Ptxは最大送信電力であり、fcは移動局の最小中心周波数である。従って、パイロットトーンのパラメータyは、
y=w*x(1:LwSamples),
LwSamples=ceil(Lw*fs)
になり、wはウィンドウサンプルのセットに対応し、
フラットトップウィンドウ関数が使用される場合、
w=flattopwin(LwSamples)
として、Mathlab(登録商標)構文で決定されてよい。
