Study On Performance Of Adaptive High-power Interference Cancellation System In Wide-Band

This paper discusses the principle and performance of multi-channels adaPtive interference cancellation system. Especially analysisand discuss the importan target cancellation ratio and cancellationbandwidth of the wide band high power interference cancellation syStems.Some actual factors to limit the raising of the cancellation ratio werepointed out. The same time, some manner to rise cancellation bandwidthwas advanced, and computer simulation and performance comparingabout which was done. Solving the contradiction betWeen the thermalnoise and high loop gain in the system, and reducing the thermal noise tothe expectation. Designing the circuits of wide band and high poweradaPtive interference cancellation system and measuring the target in thelab. Take use of the software OrCAD to optimized design the actualcircuits and simulate the performance of system.
