Communication system where uses ultra wideband pulse amplitude modulation, and driving method thereof

摘要

PURPOSE: A communication system and a driving method thereof are provided to improve stability and performance of a communication system by using two narrowband interference suppression waveforms. CONSTITUTION: A communication system(10) using ultra wideband pulse width modulation includes a signal generator, a narrowband interference waveform detecting part(20), a narrowband interference suppression waveform generating part(30), and a signal transmitter. The signal generator generates a data signal having a first frequency by using a system clock and a series. The narrowband interference waveform detecting part detects a narrowband interference waveform which gives interference influence to an original signal. A narrowband interference suppression waveform generating part generates two narrowband interference suppression waveforms which suppress the detected narrowband interference waveform. A data signal generated from the signal generator is converted into the two narrowband interference suppression waveform shape. A transmitting part obtains a signal through a receiving antenna.
