IPC: H04J11/00
Filed: 1994-09-26
Abstract: PURPOSE: To reduce multi-path disturbance without insertion of a guard interval in the OFDM modulation system. CONSTITUTION: A mapping section 1 forms complex data from transmission data. The complex data are distributed into two series and allocated to each of even nombered orthogonal carrier and odd number-th orthogonal carrier and given to an even numbered carrier IFFT section 3 and an odd numbered carrier IFFT section 4, in which the data are subjected to inverse high speed Fourier transformation in the unit of OFDM symbol and converted into complex data on time base. The complex data on time base with an even numbered carrier subjected to digital modulation are formed into a waveform in which a first half waveform for an OFDM symbol period is excluded and the same waveform as the last half waveform is interpolated to the first half waveform in the demodulator.  The complex data on time base of an odd numbered carrier subjected to digital modulation are formed into a waveform in which a first half waveform for an OFDM symbol period is excluded and the same waveform as the last half wave form is inverted and interpolated to the first half waveform in the demodulator.

Title: Solid-state laser equipment
Inventor: KATSUTA NOBUYUKI
IPC: H01S3/08
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent horizontal mode from changing in a resonator and provided a solid-state laser equipment which can stabilize its laser power. SOLUTION: A parallel flat board 7 is arranged between a nonlinear optical crystal 5 and an output mirror 6 vertically to the optical axis of a resonator. Since it is not refracted, light on the optical axis runs straight and the light of the basic wave returned by being reflected at the output mirror 6 is returned along the same incident path to the output mirror 6. Therefore, the light is not affected by the parallel flat board 7. If light is of peripheral light of the optical axis, since its incident angle to the parallel flat board 7 deviates from the right angle, the path of the basic wave returned by being reflected at the output mirror 6 is largely away from the incident path to the output mirror 6 and the light goes outside the resonator.
