| Summary: | 碩士 === 淡江大學 === 電機工程學系碩士班 === 98 === The modulation techniques in wireless communication systems usually can be classified into three classes, namely amplitude modulation, frequency modulation and phase modulation. In this report we propose a new modulation technique it uses the same concept as the phase modulation but we use different technique, in stead of the conventional pulse shaping, to generate our transmitting signal to make it easy at the receiving side to detect the transmitted signal.
At the transmitter side it is through FPGA and uses an on-off keying circuit to control the input signal, it is then in the on-off circuit to generate a phase shift keying like signal and then it is transmitted through an inductor circuit. At the receiving terminal the received signal is amplified and converted into digital signal, it is then through the FPGA circuit to decode the transmitted signal.
