New algorithm of blind sparse source separation
Zhaoshui He · Computer Engineering and Applications Journal · 2007
In this paper,the estimation of the source signals is discussed in detail.Usually,linear programming or shortest-path technique is used.Since they are all with complex computation,they are very hard to be operated.To improve the algorithm,we propose a new algorithm by setting suitable initial value direction projection by direction projection.A steepest descent algorithm is associated to estimate the source signals.The new algorithm is easy to be implemented and with fast convergent speed.The algorithm satisfies the demand of convergent speed in BSS.
