一种抑制NC-OFDM带外干扰的新方法
A New Method for Out-of-band Interference Suppression in NC-OFDM Systems
摘要
Abstract
In order to reduce the radiation of the NC-OFDM sidelobe,we use the frequency domain partial response coding (PRC) suppression method combined with dynamic deactivation of subcarriers lying adjacently to allocated license users to suppress the radiation.The impact of the spectrum position and spectrum occupancy rate on the proposes method is analyzed.Simulation results show that the joint method can reduce the NC-OFDM out-of-band interference significantly,at the same time the error performance of the cognitive users can be improved.关键词
