Description
Ni=1000k Te B、
上式で:
k=1.38×10−22ジュール/度(ボルツマン定数)
Te=(F−1)To
To=370K(摂氏100度)
F=受信器の雑音指数
B=Hzで表した周波数帯域幅
したがって、所与の信号対雑音比(SNR)に利用可能な信号帯域幅は、dBmの形態で計算することができる:
Ni(dBm)=10Log[1000k Te B]
Bについて解くと:
B=[10^(Ni(dBm)/10)]/[1000k Te]
0.3ビット/Hzが、適度な実施態様において双極性位相シフト・キーイング(BPSK)デジタル変調方式に必要な近似帯域幅である。より複雑な変調方式および回路は、より高いビット/Hz密度をもたらすことができる。同様に、スペクトル拡散技法は、より低いビット/Hz密度をもたらし、一方、システムをさらに複雑にすることを代償として、より低いSNR比においてより低いビット・エラー率をもたらすことができる。
fc=1/[2PI(L1C1)1/2]=1/[2PI(L2C2)1/2] (1)
所望の回路品質ファクタQを獲得するためのトランシーバの入力インピーダンスR1は、以下の通りである:
Q=R1/[(L1C1)1/2] (2)
より高いQの値は、らせんカプラ118と伝送線との間の結合量を増大させるが、RF信号の帯域幅を低減する。したがって、Qの適切な選択は、トランシーバが許容することができる信号の減衰量に依存する。
