Abstract EN
We propose a novel hybrid combination scheme in cooperative spectrum sensing (CSS), which utilizes the diversity of reporting channels to achieve better throughput performance.
Secondary users (SUs) with good reporting channel quality transmit quantized local observation statistics to fusion center (FC), while others report their local decisions.
FC makes the final decision by carrying out hybrid combination.
We derive the closed-form expressions of throughput and detection performance as a function of the number of SUs which report local observation statistics.
The simulation and numerical results show that the hybrid combination scheme can achieve better throughput performance than hard combination scheme and soft combination scheme.
