N2 - In this paper, an energy efficient cognitive radio system is
proposed. The proposed design optimizes the secondary user transmission
power and the sensing duration combined with soft-sensing information
to minimize the energy per goodbit. Due to the non-convex nature of
the problem we prove its pseudo-convexity to guarantee the optimal
solution. Furthermore, a quantization scheme, that discretize the softsensing
information, is proposed and analyzed to reduce the overload
of the continuously adapted power. Numerical results show that our
proposed system outperforms the benchmark systems. The impact of
the quantization levels and other system parameters is evaluated in the
numerical results.
