Title Anti-interterence Techniques in Communication System
Abstract
Today, the communication technology is developed rapidly and the research of anti-interference technology has already become an important content in communication.Through research and analysis to the various anti-interference technology in communications systems, transform domain communication systems (TDCS) has higher anti-interference performance, analyze and research the principal algorithms about basis function generation.Beeause AR estimation can bring to false spectrum peaks and fission of spectrum regions,a new algorithm based on adaptive multi-threshold is proposed and applied to TDCS.Utilizing the new algorithm threshold can be generated without the influence of interferenee’s power ,therefor estimate interference signal more effectively.At the same time,the simulation to transform domain communication system(TDCS) is carried out based on the Matlab . The simulation results show that the TDCS based on a new algorithm has a good ability to narrow-band interference suppression, compared with the original algorithm, the system greatly reduce the bit error rate, have a stronger anti-interference capability and stronger adaptability.
