Performance of UV Spread Spectrum Communication System based on LDPC Codes

In the UV scattering communication system, pulse broadening and noise will have a serious impact on the signal. LDPC code is a kind of error correcting code with excellent performance. It can improve the quality of UV communication to a great extent by combining it with spread spectrum technology which can effectively suppress multipath interference. Through the analysis and modeling of UV channel, a system scheme of LDPC + DSSS + BPSK is proposed, which can suppress multipath interference and improve the BER performance of the system.
