Filed: 1990-06-19
Abstract: PURPOSE:To process high speed data by proving a phase detection circuit detecting a phase difference between a clock signal extracted from the output data of a voltage controlled delay circuit controlling the delay quantity given to input data and a system clock signal, and generating the controlled voltage of a level corresponding to the pase difference and a low pass filter. CONSTITUTION:When the phase of the clock signal DCK with respect to the system clock signal SCK, namely, input data DTI is proceeded or delayed the control voltage Vc whose level is lower or higher than the level of a period T2 is outputted from the low pass filter 4. Then, the voltage controlled delay circuit 1 operates by the control voltage Vc in such a manner that it enlarges or reduces the passing time of input data DTI, namely, delay quantity. Thus, since input data DTI can be bit-synchronized with the system clock signal SCK, high speed data can be processed without increasing the scale of the circuit even if the precision of bit synchronization is improved.

Title: Punctured viterbi decoding method
Inventor: HATAKEYAMA IZUMI
IPC: H03M13/23
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To improve decoding precision without lengthening a pass memory for a trace-back. SOLUTION: ACS calculation based on reception data is executed in steps S1-S4. Besides, a step concerning the trace-back after a step S12 is executed by a step S11 only at the time of no punctured processing. Since a punctured pattern where data for the portion of one time point among reception data for the portion of three time points is not punctured is used here, the trace-back corresponding to data for the portion of one time point is executed. Then, decoding data for the portion of three time points including punctured data for the portion of two time points is generated by one time trace-back. Decoding error occurrence is prevented or reduced by not executing the trace-back with punctured data as a start point, which has a high probability of causing an erroneous decoding processing result.

Abstract: PURPOSE:To make an optical axis of luminous flux for beacon coincident with that of luminous flux for signal completely by providing an optical transmitter applying modulation of different frequency band from beacon and signal to a ray irradiated from a single light source and an optical receiver extracting selectively a modulation signal. CONSTITUTION:The beacon luminous flux irradiated from an opposite optical communication equipment, e.g., a luminous flux having a wavelength lambda2 turned on/off by a 5MHz clock signal is made incident in a photodiode 25 of the reception system, and converted into a 5MHz electric signal, and the beacon is amplified by a preamplifier 24 at a variable band and fed to a beacon output terminal 22 and a direction controller 40. The direction controller 40 controls the direction of luminous flux irradiated from an antenna 31 so that the electric field strength of the reception beacon is maximized. When the direction control is finished, switches 13, 23 are changed over and the transmission/reception of a PCM signal in faster speed is started. Thus, in irradiating the luminous flux for beacon as well as signal, the optical path from a laser diode 15 to the antenna 31 is made coincident completely.
