Power-Based Direction-of-Arrival Estimation Using a Single Multi-Mode Antenna
Phased antenna arrays are widely used for direction-of-arrival (DoA) estimation. For low-cost applications, signal power or received signal strength indicator (RSSI) based approaches can be an alternative. However, they usually require multiple antennas,

Performance Improvement for Wideband DOA estimation with White Noise Reduction Based on Uniform Linear Arrays [PDF]
A method is proposed for reducing the effect of white noise in wide- band uniform linear arrays via a combination of a judiciously de- signed transformation followed by highpass filters. The reduced noise level leads to a higher signal to noise ratio for
