Multi-User Joint Interference Suppression in Generalized Distributed Network

In order to solve the problem of multi-user interference among neighbor cells under generalized distributed net- work,system model of interference cell set is established,followed by two proposed algorithms for multi-user joint interference sup- pression.In which,the Crossed Iterative Joint Detection(CI-JD)algorithm performs stepwise interference cancellation among multi- users and could improve the system performance effectively with a little extra complexity,while the Global Joint Detection(G-JD) algorithm builds a unified model with multi-users'information and could not only restrain multi-user interference but also obtain di- versity gain in the process of detection.Simulation results validate the feasibility and significant effect of the two algorithms.
