Abstract :
A Matlab implementation of the MD-GSIR algorithm is presented, including an overview of the algorithm and details of the implementation. The algorithm uses a multidimensional factor graph and iterative message passing to gradually improve the signal estimation and accounts for fading in time, frequency and space dimensions. The implementation is preliminary and its goal is to allow flexible and easy enhancements and experimentation in the future.
