Generalized Memory Approximate Message Passing



Feiyan Tian , Lei Liu , Xiaoming Chen

* This article provides a universal GMAMP framework including the existing OAMP/VAMP, GVAMP, and MAMP as instances. It gives new directions to construct low-complexity AMP algorithms for unitarily-invariant systems. BO-GMAMP is an example that overcomes the IID-matrix limitation of GAMP and avoids the high-complexity matrix inverse in GVAMP
