摘要： There are provided adaptive beamforming algorithms for an adaptive array smart antenna. According to one embodiment of the present invention, the adaptive array smart antenna constructs an input signal matrix with a predetermined number of input signals, computes a transmission signal matrix that minimizes a cost function using a first steering matrix set to an initial value and the input signal matrix, computes a second steering matrix that minimizes the cost function using the transmission signal matrix and the input signal matrix, maps the second steering matrix on a unit circle, constructs a third steering matrix with the mapped values, normalizes the third steering matrix and determining whether the third steering matrix converges, and demodulates data using the transmission signal matrix if the third steering matrix converges.
