In this paper, we propose a new wideband direction-of-arrival (DOA) estimation method for wideband smart antennas based on Frequency-Domain Frequency-Invariant Beamformers (FDFIB). By appropriately designing the weights for frequency-domain beamformers at different frequencies, the frequency-invariant beam-patterns are obtained. These beamformers play a(More)
In this paper, spatial processing with lens antennas arrays for direction-of-arrival (DOA) estimation is considered. In this approach , when using the Multiple Signal Classification (MUSIC) algorithm, the dimension is reduced by the front end which performs spatial processing, resulting in increased computational speed and decreased computational load. As a(More)
F uture generations of wireless communication systems, such as fourth-generation (4G) mobile communication systems, broadband wireless access networks, are expected to provide a wide variety of services (e.g., mul-timedia, broadcasting, etc.) through reliable high-data-rate wireless channels. The high-data-rate wireless channels can be obtained with wide(More)
