In underlay spectrum access,we know that the average transmitting power of the primary user is known by the secondary user as SU can transmit data within a threshold level.but what other primary users specification or parameter or knowledge should the secondary user have to access the spectrum efficiently?
suppose if the transition probability is known by the secondary user ,then the secondary user can find a better strategy to set the threshold value to have high throughput. what other primary user information can the secondary user have ? which book or paper i should read to understand that concept?
Hello, Mr. Boni,
for the SUs, we also considered the capability of dynamically setting the center frequency of the underlay channel in order to reduce interference to primary sources. You can take a look in this work.
I hope it helps.
Regards.
