Читать книгу Dynamic Spectrum Access Decisions - George F. Elmasry - Страница 24

1 1 Part 4 of this book contains the DySPAN standards. DySPAN is selected over SAS in this book because it contains API design approaches that complement the goals of this book.

2 2 There are different types of DSA services that can be offered in a set of DSA cloud services. Part 2 of this book shows that co‐site interference avoidance can be a collection of DSA services that incrementally increases the efficiency of frequencies assignments. The consideration of blanking signal, which ensures the accuracy of sensing information, can be another type of DSA service.

3 3 DSA decisions are often needed when the radio frequency signal is compromised. The DSA control plane conditions may or may not be compromised at that time. When the DSA control plane is compromised, DSA services should be available. The response time between requesting a DSA service and granting the service should not be dependent on the DSA control plane conditions.

4 4 Some military networks can have an antijamming mode. A DSA decision can be switching from a high bandwidth normal mode to a lower bandwidth antijamming mode instead of changing the operating frequencies.

5 5 Order of time here means response time and the gap of time between two consecutive DSA service requests.

6 6 Abstracting spectrum sensing information is covered in detail in Chapter 4.
