Different adaptive processors and algorithms are presented. A detailed analysis of narrowband processor based on (LMSE) algorithm was carried. The weakness of this type of processor against broadband signals is defined. Broadband processors are verified and analyzed.Transversal filter processor is adapted and generalized to handle M sensor and J taps rather than two sensors presented by other researchers. An alternative approach to performing more efficient broadband processor is suggested with a complete mathematical model. System performance features are derived and used to evaluate the effectiveness of these broadband processors. The simulation results show that the broadband processor in conjunction with (LMCVB) algorithm has a good capability to handed different signals bandwidth.The results show that the delay sensor processor has a better performance in cancellation bandwidth interference source than the transversal filter.The results also show that the number of taps is required to compensate signal bandwidth effects is less in case of (SDL) than the case of transverse filter which means that (SDL) processor is less complex, less expensive and less computational time.
