摘要
PURPOSE: An apparatus for measuring an SNR(Signal-to-Noise Ratio) is provided to reduce quantity of calculation necessary for improving the SNR of a received signal by making it possible to estimate the SNR regardless of synchronization of carrier wave. CONSTITUTION: A calculation part(1) calculates distance of a reception signal point. A comparison part(2) compares the distance calculated by the calculation part with a certain threshold value. A counter part(3) counts the number of signal points having distance smaller than the threshold value.
