Tang Da-yu · Telecommunication Engineering · 2012
In order to solve signal interference in practical engineering and improve error-correction as well as encryption capability,a soft spectrum spreading technique combining RS error-correction coding and Walsh transform is proposed.Through RS error-correction codes generation,Walsh transform method research with help of Walsh function and composite coding,and comparison with conventional direct spectrum spreading,advantage of soft spectrum spreading technique is discussed based on Matlab simulation.Furthermore,practical engineering is also introduced.
