Описание: This SpringerBrief introduces the current research status on emerging multiple access schemes for mMTC, which provides an integrated reference for future research works. A brief introduction on mMTC scenario is provided, and then the suitable random access procedure is discussed. Various multiple access schemes for mMTC are also described and analyzed in detail. It assumes a background in communication theory and wireless communication fundamentals. With the thriving of Internet of Things (IoT) industry, an emerging scenario named massive machine-type communication (mMTC) is considered in the future 5G networks. One main challenge in mMTC is how to support massive connections with limited radio resources and low energy consumption. Therein, novel multiple access scheme is the key to overcome the challenge.This SpringerBrief targets researchers and engineers, who are engaged in 5G and future IoT related communications system. It can also be a used as a reference book or a secondary text for graduate students, who major in communications.

Описание: The Internet-of-Things (IoT) revolution has triggered the need of massive connectivity for billions of devices requiring a system capacity which is far beyond the current network designs that can be supported. This emerging requirement has reshaped the society and industry in pursuing efficient communication paradigm. In particular, massive machine-type communications (mMTC) will be a prime driver for enabling the vision of scalable IoT with heterogeneous applications, where the massive access is of paramount importance. This book discusses important massive IoT scenarios and the key technical requirements of the corresponding massive access. We review the state-of-the-art IoT standards and mMTC solutions, and summarize the limitations of the existing schemes from the perspectives of the network architecture, random access procedure, and multiple access techniques. Here, we specify the massive access challenges and reveal that the facilitation of MTC invokes a dramatically different access scheme from current ones mainly designed for human-centric communications. Moreover, we propose several promising massive access solutions to overcome the limitations, where sufficient theoretical model and algorithm design guidance are provided. Besides, detailed simulation and engineering implementation methods are also included.

Описание: This book provides a detailed overview of detection algorithms for multiple-input multiple-output (MIMO) communications systems focusing on their hardware realisation. The book begins by analysing the maximum likelihood detector, which provides the optimal bit error rate performance in an uncoded communications system. However, the maximum likelihood detector experiences a high complexity that scales exponentially with the number of antennas, which makes it impractical for real-time communications systems. The authors proceed to discuss lower-complexity detection algorithms such as zero-forcing, sphere decoding, and the K-best algorithm, with the aid of detailed algorithmic analysis and several MATLAB code examples. Furthermore, different design examples of MIMO detection algorithms and their hardware implementation results are presented and discussed. Finally, an ASIC design flow for implementing MIMO detection algorithms in hardware is provided, including the system simulation and modelling steps and register transfer level modelling using hardware description languages. * Provides an overview of MIMO detection algorithms and discusses their corresponding hardware implementations in detail; * Highlights architectural considerations of MIMO detectors in achieving low power consumption and high throughput; * Discusses design tradeoffs that will guide readers’ efforts when implementing MIMO algorithms in hardware; * Describes a broad range of implementations of different MIMO detectors, enabling readers to make informed design decisions based on their application requirements.
