“…Different shapes are presented to ensure ultra-wide band passing with high efficiency, such as rectangular, trapezoid, circular, polygonal, and elliptical antenna. For example, in [10], the author is studying a new antenna, in relative bandwidth reaches 153.22% and an efficiency of 86%, will be used for Wimax/WLAN and several wireless communication applications. In [11], an antenna was proposed for UWB applications designed for wireless communication applications, with a relative bandwidth (BPR) of approximately 119% and an efficiency of around 82%.…”

This paper proposes a method for designing a new <em>ultra wide band</em> (UWB) multiple-input multiple-output (MIMO) antenna with two and four elements. First we presented an ultra-wide band antenna we studied these performances. Then, we studied the application of metamaterials to the design of MIMO antennas for miniaturization and the performance of antennas, in order to guarantee the proper functioning of the MIMO system with a much reduced separation distance between the radiating elements (λ/12), where the coupling can be very weak. The application of these circular double ring SRRs materials on the front plan of the antenna has contributed to the increasing of the antenna performance is studied in terms of S-Parameters, efficiency, diversity gain (DG), radiation properties and envelop correlation coefficient (ECC). It offers advantages such as the reduction of weight and congestion that is beneficial for their integration into satellite communications systems.

“…In order to solve the problem of low-band spectrum scarcity and further improve system capacity and improve user data experience, the spectrum-rich millimeter wave band has been paid increasing attention as the key spectrum of next-generation mobile communication technology [1,2]. The fifth-generation mobile communication (5G) plans to use the millimeter wave frequency band in the frequency range of 6 to 100 GHz to provide higher system capacity for users in hotspots [3][4][5][6][7][8], channel measurement and measurement in several important frequency bands such as 28 GHz, 38 GHz, and 73 GHz. Modeling is underway, and the IMT-2020 (5G) promotion group also released the 5G wireless technology architecture white paper in May 2015 [9].…”

Efficient and Symmetry based precoding plays a key role in wireless communications. In order to improve the transmission performance of multi-user millimeter wave Multiple-Input Multiple-Output (MIMO) (MU-mmWave MIMO) systems, this paper proposes an analog precoding scheme for the receiver of mmWave MIMO with split sub-array hybrid analog and digital architecture. Then, we propose a hybrid analog and digital precoding algorithm based on channel reciprocity (APoCR) to maximize the spectral efficiency by utilizing the triple joint optimization problem, which can be divided into the analog and digital part. The analog combination vectors (ACVs) are obtained by the signal-to-interference-and-noise ratio (SINR) reception maximization of each downlink user and the analog precoding vectors (APVs) are obtained by the SINR reception maximization of each uplink antenna array. The digital precoder of the transmitter is designed after the analog part optimization to alleviate the interference between multiple data streams of the users. The simulation results show that the proposed precoding algorithm has a better sum rate, fast convergence, and improved SINR than the other state-of-the-art algorithms.

“…MIMO was introduced recently in UWA communication to efficiently use the acoustic bandwidth and increase the system capacity by exploiting the spatial diversity. The parallel transmission of independent data streams in MIMO improves the data rate performance [7]. The combination of MIMO and OFDM is a tempting low-complexity solution for bandwidth-efficient communications over frequency selective and bandwidth limited UWA channels [8][9][10][11][12].…”

Low-Complexity Progressive MIMO-OFDM Receiver for Underwater Acoustic Communication

Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) proves to be a better choice for high speed underwater acoustic (UWA) communication as it increases the data rate and solves the bandwidth limitation issue; however, at the same time, it increases the design challenges and complexity of the receivers. Inter-Symbol Interference (ISI) and Inter-Carrier Interference (ICI) are introduced in the received signal by the extended multipath and Doppler shifts along with different types of noises due to the noisy acoustic channel. Here we propose two iterative receivers: one is ICI unaware iterative MIMO-OFDM receiver, which uses a novel cost function threshold based soft information decision feedback method. The second one is ICI aware progressive iterative MIMO-OFDM receiver, which adapts and increases the progressions according to the level of ICI present in the received signal, while fully utilizing the soft information from the previous iterations, therefore reducing the complexity. Orthogonal Matching pursuit (OMP) channel estimation, low density parity check (LDPC) decoding and minimum mean square error (MMSE) equalization schemes are exploited by both the receivers. The proposed receivers are analyzed and compared with the standard Alamouti MIMO receiver as a reference and also compared with the non-iterative, basic turbo iterative and non-progressive iterative MIMO receivers. Simulations and experimental results prove the efficiency and effectiveness of the proposed receivers.
