Abstract
This paper presents WSK(wavelet shift keying) that can be improved to bit transmission rate in the digital communication. An algorithm of the conventional modulation is carried out that the scaling function and wavelet are encoded to 1(mark) and 0(space) for the input binary data, respectively. A new modulation technique that uses four carrier frequencies is proposed. Four carrier frequencies are defined as scaling function, inversed scaling function, wavelet, and inversed wavelet, which are encoded to 10, 11, 00 and 01 respectively. An algorithm of the proposed demodulation is decode to the original data using four correlation. As a results of simulation, we confirmed that the proposed method was improved to the performance at twice for the bit transmission rate.
