Abstract
- A frequency domain partially adaptive algorithm, called a censoring adaptive array (CAA) algorithm, is proposed to reduce the computational complexity of a frequency domain adaptive array. The CAA algorithm uses a cell averaging constant false alarm rate (CA-CFAR) processor to adapt only those weights that correspond to the frequency bins expected to contain interference. The false alarm rate also adapts according to the environment. Furthermore, a censoring spatial smoothing is proposed to combine the CAA algorithm with a spatial smoothing technique. The performances of the proposed algorithms are compared with conventional algorithms using computer simulation.
