A function A(t) in the equation I represents a constant envelope in the case of the QPSK, the accumulated value is regarded to be uniform for t=0-N/2 and t=N/2+1-N and the accumulated value is represented by a ratio of accumulated points. When the accumulated value is 1/2, the phase rotation at both ends is 1/2 and equation II is obtained. Thus, equation III is derived from the equation I. The correlation level P is expressed in equation IV and the reduction in the correlation level by a frequency offset is 1/2. and then the correlation peak detection available frequency range is doubled.

Title: Ac control circuit
Inventor: TAKAMI HIROYUKI
IPC: H05B39/04
Filed: 1989-06-27
Abstract: PURPOSE:To perform supply power regulating operation smoothly by discharging a capacitor at the end of half wave of AC source voltage thereby eliminating hysteresis between the resistance of a variable resistor and supply power. CONSTITUTION:Time constant of a resistor R2 and a capacitor C2 is set such that a three terminal switching element T3 is conducted at the end of each half wave of AC source voltage E. A capacitor C2 is charged through the resistor R2 for every half wave of the AC source E voltage, and the three terminal switching element T3 is conducted at the end of the half wave of AC source E voltage thus discharging a capacitor C1. Consequently, the capacitor C1 is discharged at the end of each half wave even if a variable resistor VR1 has resistance high enough to prevent conduction of a trigger element T2 between half waves and thereby no charge is left in the capacitor C1.
