Spectrum sensing is an important step toward enabling dynamic spectrum access in cognitive radio networks. To ensure that primary users are properly protected while maximizing the performance of secondary users, most related work considers the metrics of probabilities of missed detection and false alarm for determining optimal spectrum sensing parameters.(More)
The demand of mobile wireless communication increases year by year. To satisfy the demand, multiple radio techniques (RATs) are suggested to be integrated in the next generation wireless communication system, i.e. 5G. Wi-Fi is one candidate RAT but the anarchy of access points of Wi-Fi degrades the network performance. Software-defined wireless local area(More)
Although 3D printing is becoming more popular, but there are two major problem. The first is the slowness of the process because of requirement of processing information of an extra axis comparing to tradition 2D printers. The second is the printable dimension of 3D printers. Generally, the larger the model is printed, the larger a 3D printer has to be and(More)
Interference-aware spectrum sensing extends conventional interference-agnostic sensing by exploring the fact that missed detection does not necessarily result in outage or intolerable interference on the primary user. While related work has motivated and demonstrated the benefits of interference-aware spectrum sensing for spectrum hole discovery, the(More)
