There exist many adaptive algorithms that can be used in the adaptive antenna array. However, for the adaptive array used in an Anti-Jam GPS system, where multiple users occupy the same frequency band, the adaptive algorithm should have the ability to separate and extract each user's signal simultaneously. It is also preferred that the adaptive algorithm can work without a training sequence, i. e., the algorithm is blind. Only a few algorithms presented in the literature can satisfy the above requirements. Therefore, it is desirable for novel algorithms to be developed so a comparison between the new algorithms and the existing one can be performed such that an optimum one can be chosen.

To achieve the ambitious requirements introduced for future wireless systems, new 'intelligent' or 'self-configured' and highly efficient systems will most certainly be required. In the pursuit of schemes that will solve these problems, attention has recently turned to spatial filtering methods using advanced antenna techniques: adaptive or smart antennas. Filtering in the space domain can separate spectrally and temporally overlapping signals from multiple mobile units, and hence the spatial dimension can be exploited as a hybrid multiple access technique complementing FDMA, TDMA and CDMA.

A considerable amount of research has been done on the GPS signal acquisition process and various RFI mitigation techniques. GPS signal acquisition has been studied for feasibility in hardware and software implementation, weak signal environments and fine frequency estimation. RFI mitigation at various stages in a GPS receiver from the GPS antenna to the navigation solution has been studied extensively except for the acquisition process. RFI mitigation in the acquisition process has not been the focus of study mainly because of the few parameters controlling the acquisition process. This research studies the effect of the RFI signals in the acquisition process of a GPS receiver.
