WAVELET ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING TRANSMITTING/RECEIVING SYSTEM AND MULTIPLE INPUT MULTIPLE OUTPUT SYSTEM USING THE SAME

摘要

PURPOSE: By modulating parallel data the inverse wavelet transform and changing into serial data it can reduce the complexity of system and the wavelet orthogonal frequency division multiplex transceiving system and multiple input multi-output system effectively can diminish PAPR. CONSTITUTION: The deserializer(110) changes serial data into parallel data. The reverse wavelet packet modulator(120) modulates data outputted from deserializer the inverse wavelet transform. The parallel to serial converter(130) changes parallel data outputted from the reverse wavelet packet modulator into serial data. The compressor(140) compresses data outputted from the parallel to serial converter. Expander extends the high frequency signal received from antenna.
