Direction of arrival (DOA) estimation is a very important technology for smart antennas, which have been widely used in many applications such as radar, communication and sonar etc. Various techniques for DOA estimation have been proposed. The commonly used techniques for DOA estimation are subspace based methods, such as multiple signal classification (MUSIC) and its variations. However, these methods...
A flexible approach based on a hybrid differential evolution strategy (HDES) is developed for adaptive pattern nulling with time modulated linear antenna arrays. The HDES adjusts the least significant bits of the digital phase shifters and the on-off time sequence to minimize the total output power, deep nulls can then be placed in the direction of the interferences. Thanks to the new design freedom...
