System and method for dual chirp modulation

摘要

A system for dual chirp modulation includes a transmission unit, a receiving unit, and a transmission channel. A modulation module of the transmission unit is configured to receive binary data and modulate the binary data by a first dual chirp sequence and a second dual chirp sequence for generating an output signal. Then the output signal is converted from digital form to analog form by a digital to analog converter. A transmission channel is configured to receive the output signal converted to analog form, wherein the output signal converted to analog folio passes the transmission channel for generating a received signal. An analog to digital converter converts the received signal from analog form to digital form and a demodulation module demodulates the received signal with digital form, by the first dual chirp sequence and the second dial chirp sequence, for recovering the binary data.
