说明: 为了提高认知无线电中感知用户对授权用户(主用户) 的检测概率,提出一种新的基于循环
谱统计量的主用户信号检测算法. 该算法利用循环谱离散频域平滑方法,对信号的循环谱在循环频
率处建立合理的检测统计量,然后求解得到对应不同虚警概率的判决门限,以使感知用户能检测信
噪比更低的授权用户信号.(To increase the detection probability of sensing users for licenced users (primary signals) in
the cognitive radio , it put s forward a new primary users signal method based on cyclic spect rum statis2
tics. By using discrete f requency smoothing of cyclic spect rum , this algorithm establishes the reason2
able detection statistics on the cyclic f requency of signal cyclic spect rum , then solves and obtains the
decision threshold correspond to different false alarm probability , as a result , making the sensing users
can detect licenced users signal under lower signal in noise ratio (SNR) .)
