Latest Patents

Tae-Ryun Chang holds a patent titled "Method for processing signal of adaptive array smart antenna in array smart antenna system." This invention provides adaptive beamforming algorithms for an adaptive array smart antenna. The patent outlines a method where the adaptive array smart antenna constructs an input signal matrix with a predetermined number of input signals. It 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. Furthermore, it computes a second steering matrix that minimizes the cost function using the transmission signal matrix and the input signal matrix. The invention also includes mapping the second steering matrix on a unit circle, constructing a third steering matrix with the mapped values, normalizing the third steering matrix, and determining whether the third steering matrix converges. If convergence is achieved, data is demodulated using the transmission signal matrix.
