Abstract :
In this paper, multi-user multi-input multi-output (MIMO) precoding in the ad hoc networks is presented. The ad hoc channel model is considered and the leakage based concept extended centralized systems to distributed networks. The conventional scheme simply use own inverse channel matrices and can be suffered a noise enhancement problem. This paper presents that the leakage based precoding provides also strong performance in the ad hoc networks. It is proven using the achievable sum rate simulations.
