Abstract :
This letter presents an equivalent form of the Wang-Poor algorithm. A single matrix equation is used to generate all of the estimates simultaneously, while in the Wang-Poor algorithm a recursive technique is used to generate these estimates one by one. The new method is mathematically more compact and computationally more efficient.
