Introduction

Xin, ChunSheng; Song, Min

Pages: 1 –6

[Wireless technology plays a significant role in the national economy. The fast growing wireless devices, wireless traffic, and wireless applications create an unprecedented demand to radio spectrum. However, the radio spectrum has become a scarce resource due to the wasteful static spectrum...

Opportunistic Spectrum Access

Xin, ChunSheng; Song, Min

Pages: 7 –16

[We discuss the key components of the current de facto spectrum sharing architecture, opportunistic spectrum access, including spectrum sensing, spectrum access, and spectrum handoff. We then discuss the challenges for the opportunistic spectrum access architecture. Next, we introduce a...

Incentivized Cooperative Dynamic Spectrum Access

Xin, ChunSheng; Song, Min

Pages: 17 –31

[In the opportunistic spectrum access architecture, secondary users have to vacate from a channel once a primary user signal re-appears on the channel. However, the arbitrary disruption to secondary user communications by primary users results in poor performance for secondary users. We introduce...

Dynamic Spectrum Co-Access

Xin, ChunSheng; Song, Min

Pages: 33 –47

[We present another spectrum sharing architecture called dynamic spectrum co-access (DSCA), to enable secondary users to simultaneously access spectrum with primary users, to create a win-win situation for both. In this architecture, the secondary user uses a portion of its transmit power to...

On-Demand Spectrum Access

Xin, ChunSheng; Song, Min

Pages: 49 –64

[In this chapter, we present an application-oriented spectrum sharing architecture, called on-demand spectrum access (ODSA), to enable users to dynamically and efficiently share spectrum in a well-managed and streamlined architecture. Users can dynamically set up application-oriented virtual...

Conclusions

Xin, ChunSheng; Song, Min

Pages: 65 –66

[Thanks to the exponential growth of wireless devices and wireless traffic, the demand for radio spectrum is stronger than ever. However, the radio spectrum has been already largely licensed, due to the static spectrum allocation policy. This creates the so-called spectrum scarcity problem....
