| 内容記述 | Wireless communication has been considered as the most efficient mean of data transmission. We have been witnessed the breakthrough of wireless communication era in many manifolds, such as speech, coverage area, and stability. However, frequency bands, the resource to convey information wirelessly, are limited and expensive to be granted usage licenses. Attaining the goals of ubiquitous wireless devices will require the future wireless networks stepping forward to overcome the scarcity and expensiveness of wireless frequency bands. Thus, the future wireless networks should evolve to utilize wireless frequencies more efficiently, such as cognitive relay network where non-license users are able to transmit data in the same frequency band that officially allocated to primary users. Subsequently, the transmit power of users in a cognitive network is limited and the performance is vulnerable to impairments of transceiver hardware. This dissertation aims to analyze the performance of the cognitive relay network under the impact of transceiver hardware impairments. A case study of two-way cognitive relay network is given for further investigate the impact of transceiver hardware impairments on end-to-end outage performance and throughput. Furthermore, we provide a new relaying scheme in order to lessen the impact of transceiver hardware impairment and further boost the system performance. For the purposes, this dissertation is organized into five (5) chapters. Chapter 1: Introduction. In this chapter, multihop wireless networks and the performance metrics are overviewed. In particular, the relay networks and cognitive relay networks are presented. Moreover, the general model of the practical transceiver hardware impairment is detailed for further analysis. Chapter 2: The impact of transceiver hardware impairments on cognitive relay networks. By using the general hardware impairment model for the received signal, the closed forms of outage probability of the relay network with decode-and-forward (DF) and amplify-and-forward (AF) under the impact of transceiver hardware imperfection are derived. Based on these results, we provide further discussion on transceiver hardware selection guideline. Chapter 3: Case study: two-way cognitive relaying in energy harvesting wireless sensor networks. A two-way relay wireless sensor network equipped with RF energy harvesting node is introduced. This network is aimed to be implemented in hazardous or remote areas where power supply for the relay node is difficult to maintain. In this chapter, we consider four configurations of the network with formed by combining two bidirectional relaying protocols and two wireless power transfer policies. The detailed performance analysis of outage probability and throughput of the case-study network with four configurations are presented. Based on the analysis, we provide performance comparison between the four and suggest the network configuration with the best performance. Chapter 4: Soft information relaying protocol. The soft information relaying protocol is proposed and analyzed. The analysis shows that this relaying protocol can gradually reduce the impact of transceiver hardware impairment on cognitive relay networks. Hence, soft relaying protocol is considered as a solution for cognitive relay network with cost-effective wireless transceiver devices. Chapter 5: Overall conclusion. An overall summary of the works presented in the above is provided in this chapter. Moreover, the future related work is also discussed. The results in this dissertation acknowledge the impact of transceiver hardware impairment by presenting the reduction of outage probability and throughput of the cognitive relay network. It puts forward the consideration of including the impact of transceiver hardware impairments on wireless network performance analysis, especially for the cognitive networks of which the transmit power is limited. Furthermore, a new relaying protocol, namely soft information relaying protocol, is proposed as a solution to lessen the impact of transceiver hardware impairment. The analysis shows that the impact of transceiver hardware impairment in cognitive relay network is reduced in compared to conventional relaying schemes. As a final point, we have provided a full picture of performance analysis for the cognitive relay network under the impact of transceiver hardware imperfection and the solution to reduce the performance loss by applying soft information relaying scheme. This research would contribute to boost the development of cognitive relay networks where frequency bands are used more efficiently. | |||||||
