Title: Synchronizing holding device for receiver for spread spectrum communication
Inventor: MURAKAMI YUICHI
IPC: H04J13/00
Filed: 1986-09-30
Abstract: PURPOSE:To quicken the recovery of communication possibly by keeping a bit rate of a pseudo noise signal (PN) code series at that time for a prescribed time in detecting out of synchronism after the synchronizing locking is finished. CONSTITUTION:A spread signal distributing means 1 distributing a received spectrum spread signal and a 1st-3rd correlation detection means (2a, 3a, 6a), (2b, 3b, 6b), (2c, 3c, 6c) are provided. Further, synchronizing holding control revising and setting a bit rate sequentially and controlling the output of the synthesis means 8 to a reference level is executed consecutively and when an output of the 1st correlation detection means 6a is lower than a prescribed level, the execution of the synchronizing keeping control is stopped to start time measurement and when its output is higher than the prescribed level within a prescribed time, the synchronizing keeping control is executed again by the provision of the synchronizing control means or the like. Thus, after the synchronizing locking of a code is finished, if out of synchronism is detected, since the bit rate of the PN code series is kept for a prescribed time, the communication is restarted immediately after that point of time and the communication intermission time is short.

Title: Signal processor
Inventor: FUJIMOTO MAKOTO
IPC: H04N5/922
Filed: 1987-09-16
Abstract: PURPOSE:To decrease a noise component with high accuracy by providing a means to execute conversion to a condition in which the attenuation of prescribed quantity is executed in correspondence to the level of the frequency component of an input signal and a means to amplify a frequency component different from the above-mentioned one. CONSTITUTION:The high area frequency component of an input luminance is extracted by an HPF100a in a waveform converting circuit and supplied to a non-linear converting circuit 100b. Then, a signal to be larger than a prescribed level is outputted as it is and a signal to be smaller than a prescribed amplitude is successively attenuated. After that, the luminance signal, whose high area frequency component is suppressed with the prescribed quantity, is outputted through a coefficient multiplying circuit 100c and an adder 100d. For the signal outputted from the waveform converting circuit, the high frequency component is amplified in an emphasis circuit. Thus, since the high frequency component, which corresponds to the rising and falling edge parts of the luminance signal, is once suppressed and emphasis is loaded to the high area component of the suppressed frequency component, the noise component can be decreased.
