Abstract :
The multiple signal classification (MUSIC) algorithm has been considered to be the most effective for direction-of-arrival estimation. However, MUSIC requires considerable computation. To reduce this computational load to the extent that the sensor array system may follow rapid changes in the radio environment. The author proposes the smart MUSIC (SMUSIC) algorithm. In SMUSIC, the only requirements are the calculation of a few basis vectors and calculation of just one vector orthogonal to basis vectors. The superior characteristics of SMUSIC´s reduced processing time and high resolution are simulated numerically
