초록

This paper investigates the performance of an energy detection method with non-uniform quantization and varying number of sensing samples performed by secondary users in cooperative spectrum sensing. Generally, in cognitive radio systems, a secondary user reports the energy value obtained by a spectrum sensing method based on energy detection through a quantization process to the fusion center. In order to minimize performance loss due to the quantization errors, it is important to understand the impact of the number of quantization levels and the quantization intervals on the performance of the overall system.
