Embodiment Construction
[0058] The present invention will be further described below in conjunction with accompanying drawing.
[0059] A Cognitive Interference Coordination Method for Dense Cellular Networks Based on Random Geometry, such as figure 1 As shown, it specifically includes the following steps:
[0060] Step 1: Establish a cognitive interference coordination mechanism, including the avoidance of cross-layer interference and the coordination of same-layer interference;
[0061] Step 2: Calculate the SINR of macro users and small cell users;
[0062] Step 3: Calculate the average spectral efficiency of any specific channel in the dense cellular network;
[0063] Step 4: Design the optimal exclusive area radius, realize the trade-off between spectrum reuse rate and interference coordination, and improve the spectrum efficiency of the dense cellular network.
[0064] Dense small cell network architecture such as figure 2 As shown, consider a macro cell area with a coverage radius of 1Km,...
