Classification: CPC H  Y | IPC H

Claim 5:
6. A reconstruction device for a multi-carrier DCSK signal, comprising:
an information bit acquisition unit;
a signal modulation unit;
an original information-bearing matrix generating unit;
an information-bearing matrix reconstruction unit; and
a transmission symbol generating unit;
wherein the information bit acquisition unit is configured for acquiring an information bit sequence to be transmitted;
the signal modulation unit is configured for 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;
the original information-bearing matrix generating unit is configured for performing cross multiplication on the modulated signal matrix and a chaotic signal to obtain an original information-bearing matrix;
the information-bearing matrix reconstruction unit is configured for reconstructing the original information-bearing matrix according to a predetermined reconstruction matrix to obtain an information-bearing reconstruction matrix; and
the transmission symbol generating unit is configured for 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.
