INTERFERENCE SUPPRESSING METHOD AND DEVICE IN DYNAMIC FREQUENCY SPECTRUM ACCESS SYSTEM |
摘要 |
Disclosed are an interference suppressing method and device in a dynamic frequency spectrum access (DSA) system. The system comprises: a frequency spectrum management device, a primary system comprising a plurality of primary devices, and a secondary system comprising a plurality of secondary devices. The method comprises: transmitting position information of each of the secondary devices to the frequency spectrum management device; determining, by the frequency spectrum management device, a weight factor for a specific secondary device according to the received position formation; and performing a second-stage precoding, and in the second-stage precoding, adjusting, by using the weight factor, an estimated power of the specific secondary device leaking to the other secondary device. |
