This report presents results from simulations of adaptive jammer cancellation with different receiver arrays for Global Navigation Satellite Systems (GNSS). This is done by analyzing the performance of many, randomly generated, simulated scenarios. Results for three different hexagonal arrays of different sizes, using element radiation patterns of both simple standard type and from measurements, are given. Each antenna element channel includes a FIR filter to improve cancellation bandwidth. The purpose of this study is to be of help in the assessment of arrays with different sizes in general and the performance of these arrays in particular.
