Available in PDF, EPUB and Kindle. Book excerpt: Le multiplexage généralisé par répartition en fréquence (GFDM), une méthode de traitement par blocs de modulation multiporteuses non orthogonales, est une candidate prometteuse pour les technologies de forme d'onde pour les systèmes sans fil au-delà de la cinquième génération (5G). La capacité du GFDM à ajuster de manière flexible la taille du bloc et le type de filtres de mise en forme des impulsions en fait une méthode appropriée pour répondre à plusieurs exigences importantes, comme une faible latence, un faible rayonnement hors bande (OOB) et des débits de données élevés. En appliquant aux systèmes GFDM la technique des systèmes à entrées multiples et sorties multiples (MIMO), la technique de MIMO massif ou des codes de contrôle de parité à faible densité (LDPC), il est possible d'améliorer leurs performances. Par conséquent, l'étude de ces systèmes combinés sont d'une grande importance théorique et pratique. Dans cette thèse, nous étudions les systèmes de communication sans fil basés sur le GFDM en considérant trois aspects. Tout d'abord, nous dérivons une borne d'union sur le taux d'erreur sur les bits (BER) pour les systèmes MIMO-GFDM, technique qui est basée sur des probabilités d'erreur par paires exactes (PEP). La PEP exacte est calculée en utilisant la fonction génératrice de moments(MGF) pour les détecteurs à maximum de vraisemblance (ML). La corrélation spatiale entre les antennes et les erreurs d'estimation de canal sont prises en compte dans l'environnement de canal étudié. Deuxièmement, les estimateurs et les précodeurs de canal de faible complexité basés sur une expansion polynomiale sont proposés pour les systèmes MIMO-GFDM massifs. Des pilotes sans interférence sont utilisés pour l'estimation du canal basée sur l'erreur quadratique moyenne minimale(MMSE) pour lutter contre l'influence de la non-orthogonalité entre les sous-porteuses dans le GFDM. La complexité de calcul cubique peut être réduite à une complexité d'ordre au carré en utilisant la technique d'expansion polynomiale pour approximer les inverses de matrices dans l'estimation MMSE conventionnelle et le précodage. De plus, nous calculons les limites de performance en termes d'erreur quadratique moyenne (MSE) pour les estimateurs proposés, ce qui peut être un outil utile pour prédire la performance des estimateurs dans la région de Es/N0 élevé. Une borne inférieure de Cramér-Rao(CRLB) est dérivée pour notre modèle de système et agit comme une référence pour les estimateurs. La complexité de calcul des estimateurs de canal proposés et des précodeurs et les impacts du degré du polynôme sont également étudiés. Enfin, nous analysons les performances de la probabilité d'erreur des systèmes GFDM combinés aux codes LDPC. Nous dérivons d'abord les expressions du ratio devraisemblance logarithmique (LLR) initiale qui sont utilisées dans le décodeur de l'algorithme de somme de produits (SPA). Ensuite, basé sur le seuil de décodage, nous estimons le taux d'erreur de trame (FER) dans la région de bas Eb/N0 en utilisant le BER observé pour modéliser les variations du canal. De plus, une borne inférieure du FER du système est également proposée basée sur des ensembles absorbants. Cette borne inférieure peut agir comme une estimation du FER dans la région de Eb/N0 élevé si l'ensemble absorbant utilisé est dominant et que sa multiplicité est connue. La quantification a également un impact important sur les performances du FER et du BER. Des codes LDPC basés sur un tableau et construit aléatoirement sont utilisés pour supporter les analyses de performances. Pour ces trois aspects, des simulations et des calculs informatiques sont effectués pour obtenir des résultats numériques connexes, qui vérifient les méthodes proposées.

Book Synopsis Design and Analysis of Wireless Communication Systems with Limited CSIT Feedback by :
Download or read book Design and Analysis of Wireless Communication Systems with Limited CSIT Feedback written by and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, wireless communication industry grows tremendously and improve our life dramatically. Nowadays, as 3G systems such as WCDMA, CDMA2000 and TD-SCDMA become mature and goes into business, people start to concentrate on the reach of the next generation wireless communication systems. Next generation wireless communication systems are expected to provide high data rate and robust transmission so as to support new applications like high quality multimedia services and high speed data transfer. To meet the demands, we have to increase the operation band and/or increase the spectrum efficiency. Since spectrum is a precious resource in wireless communications, a number of new technologies are developed to enhance the spectrum efficiency such as multiple-input multiple-output(MIMO), cross layer scheduling, orthogonal frequency division multiplexing(OFDM), joint source channel coding(JSCC) etc. Most of these technologies require channel state information at the transmitter (CSIT) to enhance the performance. However, perfect CSIT is hard to obtain in practice. In FDD systems, only a limited number of bits(e.g. 6 bits for WiMAX [1]) can be allocated to carry the CSIT feedback, namely the limited feedback. Moreover, the feedback CSIT may not be error free due to the feedback channel noise. Hence the efficient utilization of the limited feedback bits and the robustness of the feedback design become important. In this Thesis, we focus on the following problems related to the design and analysis of wireless communication systems with limited CSIT feedback: optimal feedback design for MIMO-OFDM systems: We first consider error free limited feedback and propose a systematic design framework for MIMO-OFDM systems on frequency selective channels. We formulate the design problem into the classical vector quantization problem with a modified distortion metric. We find that with a small number of bits for CSIT feedback, there is significant capacity gain in the MIMO-OFD.

This book was released on 2016-06-14 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless networks represent an inexpensive and convenient way to connect to the Internet. However, despite their applications across several technologies, one challenge still remains: to understand the behavior of wireless sensor networks and assess their performance in large-scale scenarios. When a large number of network nodes need to interact, developing suitable analytical models is essential to ensure the appropriate coverage and throughput of these networks and to enhance user mobility. This is intrinsically difficult due to the size and number of different network nodes and users. This book highlights some examples which show how this problem can be overcome with the use of different techniques. An intensive parameter analysis shows the reader how to the exploit analytical models for an effective development and management of different types of wireless networks.
