Technology of Narrow-Band Interference Rejection in a DS-SS System
Yan Chen · Systems engineering and electronics · 2003
Communication equipment and systems often operate in complex electromagnetic surroundings, and are faced with more and more serious interference. Many a time, restricted by the spread spectrum(SS) bandwidth, they can not reject the external interference efficiently only by the SS gain. Thus some other methods are required to improve the insterference rejection capability the SS communication systems. Especially in the presence of strong narrow-band interference, it is of much necessity to reject the narrow-band interference. Because of the reasons above, many important techniques to reject narrow-band interference are described and analyzed.
