Abstract
a chaotic shape-forming and corresponding matched filter-based wireless communication method is provided, and the method includes that: 1) data to be transmitted is prepared; 2) chaotic shape-forming filter is performed on a digital symbol to be transmitted to generate a baseband signal; 3) the baseband signal is transmitted and transferred by use of a radio frequency component and transmitting antenna of a conventional wireless communication system; 4) a wireless signal is received by use of a conventional receiving antenna, and down-carrier process is performed on the received signal to obtain a received baseband signal; 5) matched filter is performed on the received baseband signal; 6) wireless channel estimation and multipath interference cancellation judgment threshold calculation are performed; and 7) sampling judgment is performed on an output signal of matched filter, symbol sampling is performed on the output signal of the matched filter in Step 5), and the sampled signal is judged by use of a judgment threshold calculated in Step 6) to obtain a decoded output signal.
