摘要： A metric calculating means calculates a first metric corresponding to a transmitted symbol sequence estimated by an adaptive equalizer, then calculates a second metric corresponding to a symbol sequence in which a symbol located at a position where a soft decision is made in the transmitted symbol sequence is inverted in polarity. Thereafter a subtracting portion subtracts the second metric from the first metric. Further, a multiplying portion multiplies the subtraction result from the subtracting portion by the symbol located at a position where the soft decision is made in the transmitted symbol sequence to generate a soft decision.

摘要： In a cluster ion beam irradiation apparatus including an apparatus for measuring size and energy distribution of gas cluster ions by using the time of flight (TOF) mass spectrometry, a unit for applying a retarding voltage is disposed in a stage preceding a TOF measuring instrument including a drift tube and a current measuring instrument. By measuring the size and energy distribution of the gas cluster ions and adjusting ionization conditions, cluster ions having predetermined energy and size are supplied to a work surface. In addition, a product of a pressure in an ion transportation device and an ion transportation length is controlled so as to satisfy the relation P×L≦30/N2/3/E1/2 Pa·m, where N is the size of gas cluster ions used for irradiation, and E is kinetic energy (eV) of the gas cluster ions.

摘要： The present invention relates to an optical receiver, in which the transmittance of a Mach-Zehnder interferometer can be locked at a normal operation point in a simple structure and control. A transmittance detecting circuit and a minute modulation signal detecting circuit are provided in parallel after a balanced optical receiver, and a switch is selectively connectable either a minute modulation signal detecting circuit and a transmittance detecting circuit. In the initial stage of frequency pull-in, the switch is set to connect the transmittance detecting circuit to the synchronous detection circuit. If the transmittance detecting circuit detects that the transmittance of the Mach-Zehnder interferometer at the carrier frequency becomes a desired transmittance, the connection of the switch is switched from the transmittance detecting circuit to the minute modulation signal detecting circuit.

摘要： Buffers 101 and 103 are provided in an input and an output of a signal processing circuit 102 for performing a data transformation between a first digital data signal and a second digital data signal, respectively, and data of one of the first and second digital data signals is interpolated by a data interpolation circuit 106 on the basis of a deviation between sampling frequencies of the first and second digital data signals detected by an out-of-sync detection circuit 104 on the basis of two clocks driving the buffers 101 and 103. Further, an amount of jitter between the two clocks driving the respective buffers 101 and 103 is detected by a jitter detection circuit 105 and the amount of interpolation data is controlled in the data interpolation circuit 106 on the basis of the amount of jitter.

摘要： An improved excitation signal in a low bit-rate coding device for coding a discrete speech signal sequence into an output code sequence for use in exciting a synthesizing filter, an autocorrelation function of an impulse response calculated for the synthesizing filter by using a parmeter sequence representative of a spectral envelope of the segment and a cross-correlation function between the segment and the impulse response are used to produce a sequence of excitation pulses by successively deciding locations and amplitudes of the pulses with the location of a currently processed pulse decided by the use of the locations and the amplitudes of previously processed pulses and with renewal of the previously processed pulse amplitudes carried out concurrently with decision of the currently processed pulse amplitude by the use of the previously and currently processed pulse locations. Alternatively, the currently processed pulse location and the previously and currently processed pulse amplitudes are decided by the use of the previously processed pulse locations. The parameter and the excitation pulse sequences are coded and then combined into the output code sequence. The correlation functions are preferably calculated with the segment and the impulse response weighted by weights dependent on the parameter sequence. The segment may be a frame of the speech signal sequence or a subframe of a constant or variable length.
