NC-OFDM系统中加窗技术研究
The Research on Windowing in Non-continuous OFDM Systems
摘要
Abstract
In non-continuous orthogonal frequency division multiplexing ( NC-OFDM) system, the licensed users suffer out-of-band ( OOB) interference from the rental users. In order to protect the licensed users' performance while efficiently exploiting the spectrum resources, a time-domain windowing techniques is suggested in studying the out-band interference of rental users under different windows, and the corresponding interference suppression performance is analyzed under the parameters of window functions, location and band occupancy of the licensed users. Moreover, the optimized window type is presented. The simulation results show that the time-domain windowing techniques can effectively reduce rental users' interference to the licensed users for different location and band occupancy of licensed users.关键词
