Abstract In this paper, a linearly precoding algorithm is presented based on the minimum jamming criterion for the downlink multi-element multi-user system. And by using nonlinear programming method, the closed-form expression of precoding weights is also derived, therefore reducing the complexity of the system significantly. Furthermore, due to its interference-limited property, the exact Probability Density Function (PDF) of the Signal-to-Interference Ratio (SIR) is also derived via the closed-form expression obtained, thus facilitating the analysis and application of the algorithm.
