    An Overview of OFDM-UWB 60 GHZ System in High Order Modulation Schemes
    (Institute of Electrical and Electronics Engineers Inc., 2020) Shawqi, F.S.; Audah, L.; Hamdi, M.M.; Hammoodi, A.T.; Fayyad, Y.S.; Mohammed, A.H.
    Advanced technology was needed for this within the cap of bandwidth, due to new developments in wireless networking and the increasing requirement of high data levels by consumers. One of the promising solutions is a system with 60 GHz Ultra-Wideband (UWB) that supports a data rate of up to 7 Gbps, considered 10 times faster than the Wi-Fi 802.11n data rate. The system uses advanced modulation modulations and coding systems called adaptive modulation and coding (AMC). However, inappropriate modulation level selection and coding rate can lead, in the event of radio frequency interference and a multi-way decline, to a low data rate. In fact, if non-optimum decoder due to the code's restriction duration was chosen, more output loss occurs. In this paper, we will present explain about the OFDM technology. Also, we will discuss 60 GHZ Frequency Band and all their advantage. So, we will explain the OFDM-UWB systems and convolutional coding and viterbi decoding. © 2020 IEEE.

    A Review of PAPR Reduction Techniques for UFMC Waveform
    (Institute of Electrical and Electronics Engineers Inc., 2020) Shawqi, F.S.; Audah, L.; Hammoodi, A.T.; Hamdi, M.M.; Mohammed, A.H.
    This paper addresses the usage of the Universal Filtered Multi Carrier (UFMC) band. UFMC is a multicomponent network modulation technique (5G). In this paper we discuss the different modulation technologies for 5 G technology and support the need for UFMC technology in wireless 5 G communication. Some drawbacks such as lateral band leakage, high Peak to Average Power ratio (PAPR) and spectrum utilization are used to decreases the performance of the system in 4 G OFDM modulation technique. Though, with the introduction of Internet of Things (IOT) and the transition to user-centered computing, it is difficult to utilize the OFDM methodology. There are still some problems in realistic terms of a single-carrier strategy called filter bank multi carrier (FBMC) which is stronger than OFDM. And a switch to a separate strategy named Universal Filtered Multi Carrier (UFMC) is used due to efficient usage of the spectrum by considering the formats above. This article also explains the PAPR reduction method in 5G waveform (UFMC). The usages of the UFMC waveform in 5G system to achieve the requirements are many useful than the OFDM waveform. © 2020 IEEE.

    A Survey on Multi-Objective Harmony Search-Based Clustering and Characteristics in WSN
    (Institute of Electrical and Electronics Engineers Inc., 2020) Rashid, S.A.; Audah, L.; Hamdi, M.M.; Alani, S.; Mohammed, A.H.
    Advancements in Wireless Sensor Network (WSN) technology has allowed lightweight, inexpensive sensor nodes to track diverse physical and environmental environments, data, and so forth. Wireless correspondence, and delivery. The clustering of WSNs has proved to be an efficient method for enhancing data processing and scalability for broad WSNs. Clustering often retains the sensors' minimal energy supplies. The aim of the paper to present the concept of WSN and their Characteristics and discuss the concept of the cluster in a wireless sensor network. © 2020 IEEE.
