Abstract :
In this work, a fuzzy logic system for improve the resolution in the estimation of the direction of arrival (DOA) in mobile communications, implemented on FPGA is proposed. The DOA estimation is based on a linear sensor array and a low resolution algorithm known as periodogram. The application is focused on mobile scenarios when two sources interfere between them in a spatial way over the sensor array. In order to gain robustness, system is trained based on the ANFIS architecture and a set of training data obtained from a channel model which take into account multipath effects and SNR variations in the signals detected by the sensors
