摘要:
A pre-processing method and system for cooperative communication are provided. The method includes: after obtaining channel matrices collected by a Base Station (BS), obtaining Multiple-Input Multiple-Output (MIMO) Cooperation Area (CA) information, in which the MIMO CA information includes cooperation information between BSs, and the cooperation information between the BSs is used to determine an interference relation between MIMO CAs; combining the channel matrices of a User Equipment (UE) according to the interference relation between the MIMO CAs; and performing pre-coding computation of the UE by using the combined channel matrices.

The invention provides an injection molding method of stone-based composite material and equipment thereof, wherein the method comprises the following steps: a. putting raw materials into a charging device and then pushing the raw materials into a preforming machine barrel of a preforming device by a pressing component in the charging device; b. keeping the temperature being between 15° C. and 55° C. and compacting the raw materials with the rotation of a preforming screw and transporting the raw materials into a collecting block; c. injecting the raw materials into a mold through a mold gate under the injection force of 50 Mpa to 180 Mpa; d. keeping the temperature of the mold between 140° C. and 200° C. and curing time between 40 seconds and 300 seconds; and e. opening the mold to get the product. The invention has the advantages of simple production process, high acceptance rate of products manufactured, high production efficiency and low production cost. The product has the advantages of high mechanical strength, good fire resistance, thermal stability, corrosion resistance and electrical property, low cost and the like. The product is capable of substituting the majority of thermoset plastics and thermoplastics, thus reducing the usage amount of plastic products and providing powerful support and safeguard for creating resource-conservation and environment-friendly industry.
