Joint downlink spectrum resource block(SRB) and power allocation was studied based on OFDMA n cog-nitive small cell networks. In a distributed framework. small cell base stations (SCBS) could share free spectrum re-sources with open access to maximize their energy efficiency (EE) respectively. The competition among SCBS made the dynamic resources allocation problem be modeled as a non... https://chefesquipmenters.shop/product-category/wall-mount-shelving/
