Abstract

A novel approach of generating composite chaotic spread spectrum sequence is proposed. This algorithm creates the spread spectrum sequence by quantifying the multiplication result of two independent chaos sequences, such as the Tent chaos sequence. The frequency response and noise characteristics of power line communication (PLC) channel are researched, in order to build the typical channel model of PLC. Experimental result shows that the direct sequence spread spectrum (DSSS) system using the composite chaotic sequence generated by the proposed algorithm, can guarantee the same BER on the condition that its SNR is 3dB lower than the DSSS system using single sequence.
