| Abstract: | A novel adaptive antenna array of interference cancellation for a GPS receiver is presented.The simulation processes of its radiation pattern and the SINR of output signals(signal-to-interference and noise ratio) are given.With the same signal environment,the performance of this antenna array is compared to the other two antenna arrays---the uniform linear array and the uniform circular array.The result shows that,by using this novel antenna array,the radiation pattern can be optimized,and the SINR of outpu... |
