A New Achievable Rate Region for the Cognitive Radio Channel
Abstract— The cognitive radio channel (CRC) refers to a communication model in which two senders attempt to communicate with their respective receivers simultaneously through a c...

Achievable rates for cognitive radios opportunistically permitting excessive secondary-to-primary interference
Abstract--We propose a cognitive radio system in fading environments where the secondary sender opportunistically violates the secondary-to-primary (S-P) interference power limit. ...

Cognitive radios with multiple antennas exploiting spatial opportunities
In this paper, the achievable rates of the so called "multiple-input multiple-output interference channel", exploited by a couple of single antenna primary terminals and...

Achievable Rates for the Three User Cooperative Multiple Access Channel
— For a three user Gaussian multiple access channel (MAC), we propose a new superposition block Markov encoding based cooperation scheme. Our scheme allows the three users to sim...

Simple Channel Sensing Order in Cognitive Radio Networks
— In cognitive radio networks (CRNs), effective and efficient channel exploitation is imperative for unlicensed secondary users to seize available network resources and improve ...
