This paper investigates the maximum stable throughput of a cooperative\ncognitive radio system with energy harvesting Primary User and Secondary User.\nEach PU and SU has a data queue for data storage and a battery for energy\nstorage. These batteries harvest energy from the environment and store it for\ndata transmission in next time slots. The SU is allowed to access the PU\nchannel only when the PU is idle. The SU cooperates with the PU for its data\ntransmission, getting mutual benefits for both users, such that, the PU\nexploits the SU power to relay a fraction of its undelivered packets, and the\nSU gets more opportunities to access idle time slots.\n
