Near-optimal practical convergent method for interference alignment in MIMO interference channels
- Tao Y.

A practical distributed GaussâNewton method for the near-optimal computation of interference alignment solutions is proposed, based on the block-wise structure of Jacobian matrix of the residual interference function. Also, a simple practical matrix inverse computation algorithm to solve the rank-deficient problem due to the interference sparse matrix is adopted. This proposal achieves convergent performance comparable to centralised GaussâNewton method, with the major advantage of being practically implemented in a distributed manner.View Original Article
