  • Patent number: 8755468
    Abstract: A received pulse signal based on an on-off keying modulation scheme is alternately sampled by AD conversion sections operated by a clock signal whose frequency is one-half of a transmission rate. In the synchronization, amounts of delay in sampling timing adjustment sections are made different from each other, whereby phases of two different points in a symbol pulse are sampled. An amount of delay in a variable delay section is adjusted in accordance with a result of comparison of the sampled values, thereby achieving synchronization. At the time of demodulation, the amount of delay in the variable delay section is held, and the amounts of delay in the sampling timing adjustment sections are switched to the same value, and the symbol pulse is alternately sampled. The sampled values are subjected to threshold value determination, and the determination result is subjected to parallel-to-serial conversion, whereby a demodulation output is acquired.

  • Patent number: 8145143
    Abstract: When a power supply switch is turned on and an RF signal and an LO signal are input to a bipolar transistor, a mixed signal of both signals is output as an IF signal. When the power supply switch is turned off, the bipolar transistor operates as two diodes connected between a base terminal and an emitter terminal and between the base terminal and a collector terminal. When the IF signal and the LO signal are input, the input signals are mixed with each other by the diodes and the RF signal is output. Accordingly, one frequency conversion is performed by the use of one frequency converter, an external circuit such as a signal path switching switch is not necessary.

  • Patent number: 8130883
    Abstract: A pulse signal reception device of a comparatively simple configuration detects a signal sampled at an optimal clock timing for a pulse modulation signal having a signal width shorter than a symbol frequency. In this device, a time division unit (103) samples a data signal at a clock signal rise edge and outputs the sampled data signals to counters (104-1 to 104-3), respectively. The counters (104-1 to 104-3) count the number of High levels when the data signal becomes High level within a predetermined period, and a maximum value detection unit (105) outputs maximum data string information on a data string counted by a counter in which the maximum number of High levels has been detected among the counters (104-1 to 104-3) to a selection data judgment unit (106). The selection data judgment unit (106) judges which data string sampled at a particular timing is to be selected as a demodulation data string.
