Outage Performance of Cognitive Radio with Multiple Receive Antennas

IEICE Transactions on Communications, 2008
Outage performance of cognitive radios is analyzed in this paper. The scenario under consideration requires the cognitive radio to sense whether the primary user (PU) link is free (i. e. a spectrum hole exists) before making an active transmission using that link. Multiple antennas are available at the cognitive radio link to provide array gains at the

Wireless Powered Cognitive Cooperative Networks: Outage Performance

2019 13th International Conference on Signal Processing and Communication Systems (ICSPCS), 2019
This paper jointly studies cognitive radio (CR) and non-orthogonal multiple access (NOMA) networks by adopting an energy restricted amplify-and-forward relay. We study the outage performance of NOMA secondary destination users (U 1 and U 2 ). Then, power allocation (PA) factors based on the NOMA users’ outage fairness are evaluated for different ...

Outage performance of multi-antenna multicasting for wireless networks

IEEE Transactions on Wireless Communications, 2009
Wireless cellular networks often need to convey the same data to multiple users simultaneously. This kind of transmission is known as physical layer multicasting. Unfortunately, when any user fails to receive the data correctly, the information must be retransmitted to all the users, resulting in a waste of radio resources.

Secrecy outage performance of MISO wiretap channels with outdated CSI

2014 IEEE International Conference on Communications Workshops (ICC), 2014
In this paper, the secrecy outage performance of a multiple-input single-output (MISO) wiretap channel is investigated. Different from previous works, we assume that the legitimate transmitter employs maximal-ratio transmission (MRT) beamforming scheme with outdated channel state information (CSI) of the main channel.
