Claim 0:
1. A reconstruction method for a multi-carrier Differential Chaos Shift Keying (DCSK) signal, comprising:
acquiring an information bit sequence to be transmitted;
processing the information bit sequence by serial-to-parallel conversion; and inputting a processed information bit sequence into a modulator for modulation to obtain a modulated signal matrix;
performing cross multiplication on the modulated signal matrix and a chaotic signal to obtain an original information-bearing matrix;
reconstructing the original information-bearing matrix according to a predetermined reconstruction matrix to obtain an information-bearing reconstruction matrix; and
generating a transmission symbol according to the information-bearing reconstruction matrix and a reference signal matrix in combination with frame structure information of the transmission symbol; and sending the transmission symbol to a receiving end via a wireless network to enable the receiving end to demodulate a received signal according to the predetermined reconstruction matrix.
