Title: Spread spectrum signal receiver
Inventor: OE ICHIRO
IPC: H04B1/7085
Filed: 1993-02-22
Abstract: PURPOSE:To prevent a phase locked loop from being locked while a phase of a sender side PN code and a phase of a receiver side PN code are deviated when synchronization is kept by the carrier lock tracking system (coherent carrier tracking system). CONSTITUTION:Phase relation among a sender side PN code PNT and a carrier S2 in a spread spectrum signal is kept constant. Phase relation between a receiver side PN code PNR and a reference signal S7 is kept constant at a receiver side. The spread spectrum signal is subject to inverse diffusion processing by an inverse diffusion processing device 35. A synchronization acquisition means 37 allows a switch 40 to throw to the position of a contact (b) to close a phase locked loop 44 in a timing when both the PN codes are synchronized thereby keeping synchronization. After the synchronization is finished, a level detector and a control means 72 detects a correlation output and controls a delay of a variable delay means 70 to maximize the level thereby adjusting the relation of phases of the receiver side PN code PNR and the reference signal S7.

Title: Digital r/d converter
Inventor: SUGANUMA AKIRA
IPC: G01D5/245
Filed: 1990-03-12
Abstract: PURPOSE:To remarkably simplify the assembly work and to improve the reliability by composing all the circuit systems except an A/D converter of digital circuits in the structure of a gate array. CONSTITUTION:A synchronous signal 1a is converted to resolver signals 1b, 1c by a Scott transformer 1. The signals 1b, 1c are digitalized by A/D converters 10, 11 and fed to a quadrant selection circuit 2. A first output A obtained in the circuit 2 is compared at 12 with a second output B which is obtained at 13 by multiplying the first output A with cos theta. As a result, an up pulse 14a is input to a counter 15 from a first gate 14. When A=B, generation of a pulse is stopped. If A<B, a down pulse 16a is input from a second gate 16 to the counter 15. Therefore, the operation of the circuit systems proceeds until the outputs A, B are agreed at the comparator 12. When generation of a pulse is stopped, theta becomes equal to phi thereby obtaining a digital output phi, i.e., an output phi. The other circuit systems than the A/D converters are constituted of digital circuits into the structure of a gate array.
