The concept of energy-aware communications has spurred the interest of the research community in the most recent years due to various environmental and economical reasons. It becomes indispensable for wireless communication systems to shift their resource allocation problems from optimizing traditional metrics, such as throughput and latency, to an environmental-friendly energy metric. Although cognitive radio systems introduce spectrum efficient usage techniques, they employ new complex technologies for spectrum sensing and sharing that consume extra energy to compensate for overhead and feedback costs. Considering an adequate energy efficiency metric-that takes into account the transmit power consumption, circuitry power, and signaling overhead-is of momentous importance such that optimal resource allocations in cognitive radio systems reduce the energy consumption. A literature survey of recent energy-efficient based resource allocations schemes is presented for cognitive radio systems. The energy efficiency performances of these schemes are analyzed and evaluated under power budget, co-channel and adjacentchannel interferences, channel estimation errors, quality-of-service, and/or fairness constraints. Finally, the opportunities and challenges of energy-aware design for cognitive radio systems are discussed.

“…In addition to selfinterference at the BS, the optimization problem is exacerbated by the co-channel interference (CCI) caused by the UL users to DL users. Sum-rate maximization for FD multi-user systems has been investigated in [2], [27]- [29]. However, the CCI is not taken into account in [27], single-antenna users are assumed in [2], and these works [2], [27] and [28] did not consider any transmitter/receiver distortion.…”

Abstract-We study two scenarios of full-duplex (FD) multipleinput-multiple-output cognitive radio networks: FD cognitive ad hoc networks and FD cognitive cellular networks. In FD cognitive ad hoc networks (also referred as interference channels), each pair of secondary users (SUs) operate in FD mode and communicate with each other within the service range of primary users (PUs). Each SU experiences not only self-interference but also interuser interference from all other SUs, and all SUs generate interference on PUs. We address two optimization problems: one is to minimize the sum of mean-squared errors (MSE) of all estimated symbols, and the other is to minimize the maximum per-SU MSE of estimated symbols, both of which are subject to power constraints at SUs and interference constraints projected to each PU. We show that these problems can be cast as a second-order cone programming, and joint design of transceiver matrices can be obtained through an iterative algorithm. Moreover, we show that the proposed algorithm is not only applicable to interference channels but also to FD cellular systems, in which a base station operating in FD mode simultaneously serves multiple uplink and downlink users, and it is shown to outperform HD scheme significantly.

Abstract-Nowadays, the advancement of Wireless Local Area Network (WLAN) technology has developed very rapidly because it is very practical and has effective mobility level. In practice, there is a major problem in wireless communications systems, which is fading. Fading can cause information signal power decreasing. Fading can be overcome using a cooperative communication system, which is a method that utilizes antenna from other users (relays), using principle of diversity, hence the performance of wireless communication system is improved. A relay has several protocols on cooperative communication system, such as Amplify and Forward (AF), Decode and Forward (DF), and Compress and Forward (CF). The AF protocol is divided into two types: Non-Orthogonal Amplify and Forward (NAF) and Orthogonal Amplify and Forward (OAF). In this paper, the performance comparison of two-way NAF and OAF in terms of outage probability, throughput, and spectral efficiency is investigated. The method used is computer simulation with system modeling and performance analysis. The simulation results show that OAF protocol can minimize outage probability and increase throughput and spectral efficiency, compared to NAF protocol on two-way WLAN cooperative network. Sistem komunikasi kooperatif adalah salah satu solusi untuk mengatasi masalah fading, yaitu dengan memanfaatkan antena dari pengguna lain dengan prinsip teknik diversitas untuk mendapatkan suatu antena virtual (relay), sehingga dapat meningkatkan kinerja pada sistem komunikasi WLAN [5]. Relay berfungsi untuk membantu meneruskan sinyal informasi yang dikirimkan secara broadcast dari sumber ke tujuan [6]. Dengan demikian, mekanisme relay pada sistem komunikasi kooperatif mempunyai peran penting dalam meningkatkan kinerja sistem komunikasi WLAN. Ada beberapa protokol relay pada sistem komunikasi kooperatif yaitu amplify and forward (AF), decode and forward (DF), dan compress and forward (CF) [7]. Pada metode AF, relay menguatkan sinyal informasi yang diterima dari sumber dan kemudian diteruskan ke tujuan [8]. Metode ini lebih praktis karena sangat sederhana dan mudah untuk diimplementasikan, memiliki kompleksitas komputasi dan delay yang rendah [9]. Metode AF dapat diklasifikasi dalam dua metode yaitu NonOrthogonal Amplify and Forward (NAF) dan Orthogonal Amplify and Forward (OAF) [10]. Intisari-Untuk mengevaluasi kinerja jaringan sistem komunikasi kooperatif, dilakukan pengukuran tingkat outage probability yang didapatkan pada saat sinyal informasi ditransmisikan ke tujuan. Semakin rendah outage probability yang didapatkan, maka throughput dan efisiensi spektral juga akan semakin meningkat [11]. Penggunaan mode full-duplex untuk memperoleh efisiensi spektral yang tinggi telah dikaji pada Kurnia Rizki: Perbandingan Kinerja Non-Orthogonal dan ...
