A new constrained fast null steering algorithm

A new algorithm is presented based on the constrained fast null steering algorithm. The structure of this new algorithm is simpler than that of the tree structure of the constrained fast null null steering. A multiplier, which is inserted in the structure, multiplies the output of any summing points with the main output. The function of the multiplier is to transfer a zero when occurring at any summing points to the main output. Numerical evaluation proved the validity and simplicity of this algorithm using 3, 4, and 5 element arrays. Additionally, the new algorithm has the ability to null N+1 interference using N+1 element arrays.
