In order to solve the problem of multi-user interference among neighbor cells under generalized distributed network, system model of interference cell set is established, followed by two proposed algorithms for multi-user joint interference suppression. 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 diversity gain in the process of detection. Simulation results validate the feasibility and significant effect of the two algorithms.
