  • Patent number: 8073018
    Abstract: Jitter and waveform are improved by reducing the wavelength spectrum width of a laser beam pulse. In a laser pulse generating apparatus according to the present invention, a semiconductor laser device, a polarization maintaining optical fiber, an optical reflection filter having bandpass characteristics using an FBG whose passband can be changed by changing a tension, and an optical isolator are connected via an optical fiber. A driving circuit drives the semiconductor laser device to generate a pulse. The optical reflection filter performs filtering by transmitting a specific component of the wavelength spectrum of the pulse, reflects a portion of the optical power, and outputs the remaining optical power except the reflected portion to the outside via the optical isolator. The reflected pulse is fed back to the semiconductor laser device to thereby reduce the wavelength spectrum width of the laser beam, and improve the jitter and waveform.

    Abstract: A reception program maps, by PC mapping, the values of message data to symbol x, which describes the combinations of Mp carrier waves of Mc carrier waves with value-1 bits corresponding to the carrier waves to be transmitted, and receives the transmit signal created by performing transformation processing thereon to sample y. A matrix computing portion performs transformation processing on sample y? in a parallel form including an unnecessary signal component to symbol z?. A first decoding portion sequentially performs maximum likelihood value decoding on groups of M bits of symbol z? and finally decodes all of the symbol z? to symbol x?. If the symbol x? includes Mp value-1 bits, a second decoding portion handles the symbol x? as the final decoding result and if not, the second decoding portion performs maximum likelihood decoding on the entire symbol z? to obtain the final decoding result.
