ABSTRACT:
A UWB wireless communicating system is provided. When a process of the system is started, an initial value x0is set to a storing portion. An output of the storing portion is supplied to a mapping portion that performs a calculation using a P-th order Chebyshev polynomial as a map. In addition, the output of the storing portion is returned to the storing portion. A generated chaotic sequence is stored in a pulse interval converting portion. The pulse interval converting portion converts a linear sum G1(x) of the Chebyshev polynomial into a pulse interval value t. An output of the pulse interval converting portion is supplied to a pulse output portion. A pulse sequence having a pulse interval tiinto which the value of a liner sum G1(xi) has been converted is output. The output pulse sequence is supplied to the UWB wireless communicating system.
