Li Li · Hebei Journal of Industrial Science and Technology · 2011
The multi-access interference and quality of communication system can be greatly improved by beam forming when smart antenna is adopted.An improved SMI-LSCMA beam forming algorithm is proposed,in which the spread spectrum sequence of the given user's signal is used to lock the signal,thus accelerating the convergence of the weight value update algorithm.The simulation experiments show that the algorithm has good ability in beam forming and higher output SNR.
