Abstract:

Adaptive algorithm is the key technology in smart antenna array system. Fast convergence and small steady state error will be the main factors in beamforming when applying the algorithm to form optimal weight vector. Based on these facts, various step size and transform domain have been added into the former LMS algorithm. By reusing the array input signals and training sequence as reference signal, convergence can be achieved in a short training sequence, thus the transmission efficiency can be improved. According to MATLAB simulation result, the new algorithm has faster convergence speed and smaller steady state error to achieve an optimal beamforming performance.
