**zero forcing mse**

In designing equalizer, what is the difference between zero-forcing algo and MSE algo?

To me, it looks no big difference. According attached fig of text, the difference lies in that MSE algo will "multiply" XT in both sides of equations, compared with zero-forcing algo.

If X is square matrix, we can find (XT)-1, then these two algos should be the same.

If X is not square, then MSE will have advantage of getting longer C matrix, with same information.

Is that right? any other difference?
