A survey of interference suppression technology for spread spectrum communication
Spread spectrum communication interference suppression is a key technology for ensuring communication efficiency in communication countermeasure,which is of great significance for improving the system anti-interference ability.The research progress of time-domain interference suppression technology and transform domain interference suppression technology in direct sequence spread spectrum(DSSS)communication and frequency hopping spread spectrum(FHSS)communication was reviewed.The challenges and shortcomings of the two types of interference suppression technology were analyzed in detail.Compressive Sensing(CS)technology provides a new approach to address the shortcomings of the above methods.The research on interference suppression in spread spectrum communication can be extended to the compressed domain by utilizing CS.The latest development of spread spectrum communication interference suppression in compressed domain was described systematically from three aspects,such as interference detection,interference parameter estimation and interference suppression.By analyzing the key problems to be solved in the next step of compressed domain interference suppression,the future research direction was prospected.
