Abstract :
The effect of signal, noise and interference correlation on the performance of ULMS algorithm is studied. It is observed that the algorithm performance is greatly deteriorated with very high total correlation. The effects of different correlations are different. The signal correlation increases the MSE more than noise and interference correlations. The interference correlation affects the null-forming capability of the beamformer more than other correlations.
