Measuring device for carrier wave phase disturbance
专利汇可以提供Measuring device for carrier wave phase disturbance专利检索，专利查询，专利分析的服务。并且PURPOSE:To measure frequency offset and carrier phase jitter free from the effect of the inter-code interference, by estimating the squared mean value of the volume due to noise and the inter-code interference from the component owing to a frequency offset and the squared mean value of a phase control signal dimenated DC component. CONSTITUTION:An error signal epsilonK supplied through a terminal 5 is multiplied by the complex conjugation of aK supplied from a terminal 7 at a multiplier 101, and the real part is squared by a squaring device 102. The output of a mean value operator 103 holds the result of the preceding operation for a time LT under an operation, and the value is shown by an equation I . Then the signal supplied through a terminal 14 is calculated for its mean value by a mean value operator 113, and this value equals to the frequency offset value as shown by an equation II. While the effect of offset is eliminated by an integrator 105 for the signal supplied through a terminal 18, and the mean value of this signal is calculated by a mean value operator 106. Then the estimated carrier phase jitter amount is calculated as shown by an equation III by means of a subtractor 107, a squaring device 108 and a mean value operator 109. As a result, the dispersion of only the phase jitter can be obtained at the output of a subtractor 110.，下面是Measuring device for carrier wave phase disturbance专利的具体信息内容。
