This book systematically summarizes the current research status of non-reconfigurable spectrum sensing. Non -reconfigurable spectrum sensing algorithms were derived and performance simulations were conducted for different scenarios. The proposed non-reconfigurable spectrum sensing algorithm can reduce the amount of computational data, overcome noise uncertainty, and improve the performance of the algorithm under low signal-to-noise ratio. The research results of the monograph have high theoretical research significance and practical application value, providing strong technical support for the development and implementation of intelligent communication.
