“…6 it can be observed that the polynomial g 1 (D) requires the fewest decoding iterations to reach the top right corner at [1,1] for both SNR values. Since g 2 (D) requires fewer decoding iterations to reach the [1,1] corner, we may conclude that it outperforms g 3 (D). This shows that the EXIT chart based performance prediction agrees with the MItrends of Fig.…”

“…Fortunately, the performance of wireless systems can be enhanced using iterative decoding, where extrinsic soft information is exchanged between the constituent receiver components [3]. The increased tele-traffic has led to the development of new enabling techniques operating at increased millimetre wave carrier frequencies, where more bandwidth is available for small cells [1,2]. These advances will improve the area spectral efficiency in tele-traffic hot spots, such as stadiums, shopping malls etc.…”

Abstract-A delay of less than one millisecond is required by low-latency 5G wireless communication systems for supporting the 'tactile' Internet. Hence, conventional initial synchronisation cannot be readily employed because of its potentially excessive delay. In this paper, an EXtrinsic Information Transfer (EXIT) Chart assisted approach is used for the convergence analysis of m-sequences using Recursive Soft Sequence Estimation (RSSE) in the context of Nakagami-m fading channels. Explicitly, the novelty of our work is based on employing a new type of EXIT Charts operating without using interleavers. This is a challenge, because the original EXIT charts rely on the employment of long, high-delay interleavers for ensuring that the inputs to the decoders become uncorrelated. We then evaluate the performance of various classes of m-sequences with the aid of the proposed EXIT charts and demonstrate that the m-sequences generated by the lower-order polynomials maximise the mutual information more promptly with the aid of our RSSE scheme than those, which belong to a higher-order polynomial.

“…As a truly revolutionary paradigm shift [1], [2], wireless technology relying on radio waves has become an integral part of our everyday life, facilitating basic services, such as making a phone call or sending a message, as well as nearfield-communication-aided mobile payment. The radio waves occupy the 3 kHz∼300 GHz electromagnetic band, which has been widely used for communication purposes.…”

Abstract-In order to counteract the explosive escalation of wireless tele-traffic, the communication spectrum has been gradually expanded from the conventional radio frequency (RF) band to the optical wireless (OW) domain. By integrating the classic RF band relying on diverse radio techniques and optical bands, the next-generation heterogeneous networks (HetNets) are expected to offer a potential solution for supporting the ever-increasing wireless tele-traffic. Owing to its abundant unlicensed spectral resources, visible light communications (VLC) combined with advanced illumination constitute a competent candidate for complementing the existing RF networks. Although the advantages of VLC are multi-fold, some challenges arise when incorporating VLC into the classic RF HetNet environments, which may require new system architectures. The user-centric (UC) design principle for VLC environments constitutes a novel and competitive design paradigm for the super dense multi-tier cell combinations of HetNets. The UC concept may be expected to become one of the disruptive techniques to be used in the forthcoming fifthgeneration era. This paper provides a comprehensive survey of visible-light-aided OW systems with special emphasis on the design and optimization of VLC networks, where the radically new UC design philosophy is reviewed. Finally, design guidelines are provided for VLC systems.
