Filed: 1990-02-14
Abstract: PURPOSE:To release undesired synchronization lock or to prevent mis-locking by storing a prescribed phase state of a pseudo noise generator, controlling the pseudo noise generator by the stored phase and deciding the threshold level from a correlation output. CONSTITUTION:When a PN code is 3 bits as 011, a phase control signal tauof a PN code is shifted as 0, 1, 2 and a correlation output is changed as r0, r1, r2, then the correlation values outputted from an integration device 26 are C0, C1, C2. Thus, a peak hold circuit 36 receiving the correlation value holds the maximum correlation C2 as rMAX and outputs a hold trigger to a phase hold circuit 42 and the circuit 42 stores a value  tau=2 at that point of time. The average value calculation circuit 38 divides the integration device output by bit number of the PN code for each period of the PN code to calculate and output the correlation output rN' per bit unit. A threshold level decision circuit 34 decides a threshold level rTH based on the inputted value and one period signal from a search control circuit 40 and outputs the integration device output  tau to the circuits 32, 42.
