Abstract:

As spectrum sensing detects the presence of a primary user (PU) signal, an efficient and reliable spectrum sensing scheme plays a critical role in cognitive radio (CR). For this purpose, a sequential sensing technique is introduced to reduce the sensing time to its minimum value while maintaining the desired detection performance. However...More
