This paper presents a simple method of internal channel calibration for MIMO interference networks to maintain TDD channel reciprocity. The method works for algorithms requiring channel reciprocity. In particular, it is shown how the method works for the distributed implementation of the Dual Link algorithm, which is a very fast and provably convergent algorithm for optimal interference management.
