摘要： A communication system includes a modulating circuit to increase the amount of information to be transmitted, a transmitting apparatus capable of easily generating a desired waveform even for any very short wavelets, a receiving apparatus capable of easily separating wavelets even if the intervals thereof are narrow. The modulating circuit includes clock generating, transmission signal generating, control signal generating, delay and wavelet generating parts. The clock generating part generates a clock signal at predetermined time interval “Tp”. The transmission signal generating part generates a transmission signal at interval “Tp”. The control signal generating part outputs a control signal of a predetermined duration based on the clock signal. The delay part generates the control signal as a delay signal that has been delayed by a delay amount based on the transmission signal. The wavelet generating part generates a wavelet at the generation timing of the delay signal.

摘要： A master side communication apparatus and a slave side communication apparatus wherein the structure of a receiving part of the slave side communication apparatus is simplified to achieve a reduced size, a reduced power consumption and a reduced cost. The master side communication apparatus performs a communication in synchronism with the slave side communication apparatus having no synchronization timing adjusting function. A transport signal generating timing adjusting part of the master side communication apparatus acquires, from the slave side communication apparatus, synchronization signal generation timing information used when the slave side communication apparatus receives the transport signal from the master side communication apparatus. The transport signal generating timing adjusting part varies and adjusts, based on the acquired information, the transmission timing of the signal to be transmitted to the slave side communication apparatus. A transmitting part transmits the transport signal at the adjust transmission timing. The occurrence timing of the transport signal is varied and adjusted until the slave side communication apparatus becomes able to receive the transport signal from the master side communication apparatus.

摘要： An impulse radio communication device includes a wave detector for generating a detected signal, a switching section for selecting either a received signal or the detected signal in accordance with an external control signal and outputting it as a demodulation target signal, a reference waveform generating section synchronized with the demodulation target signal and generating a reference waveform signal having a different waveform in accordance with the external control signal, a demodulator for generating a demodulated signal from the demodulation target signal in accordance with the reference waveform signal, and a decoding section for decoding received data from the demodulated signal. This impulse radio communication device switches the demodulation target signal and the reference waveform signal simultaneously in accordance with a receiving and synchronizing state. This makes it difficult that synchronization is pulled in a correlation position having low electric power, and can reduce a acquisition time.

摘要： A pulse modulation type transmitter apparatus and a pulse modulation type receiver apparatus wherein both a fast synchronization establishment and a low power consumption of a synchronizing part can be achieved at the same time and wherein the data transmission/reception can be performed soon after a commencement of communication, and further a fast data transmission and a low power consumption can be achieved. A first template signal (1006), which is generated based on a separately transmitted RF frame synchronization signal (1005), is used to generate a frame synchronization signal (1009), and a second frame synchronization timing adjusting part (150) is used to synchronize the frame synchronization signal (1009) with a received RF data signal (1004). Then, a synchronization detection is performed, whereby a prompt pulse acquisition and a prompt pulse phase acquisition can be achieved. After the establishment of frame synchronization, a template switching part (142) is used to switch from the first template signal (1006) to a second template signal (1007) that has been already synchronized with the first template signal (1006). Then, a synchronization detection is performed, whereby the frame synchronization can be maintained.
