Positioning in Wireless Communications Systems explains the principal differences and similarities of wireless communications systems and navigation systems. It discusses scenarios which are critical for dedicated navigation systems such as the Global Positioning System (GPS) and which motivate the use of positioning based on terrestrial wireless communication systems.The book introduces approaches for determination of parameters which are dependent on the position of the mobile terminal  and also discusses iterative algorithms to estimate and track the position of the mobile terminal. Models for radio propagation and user mobility are important for performance investigations and assessments using computer simulations. Thus, channel and mobility models are explored, especially focussing on critical navigation environments like urban or indoor scenarios.Positioning in Wireless Communications Systems examines advanced algorithms such as hybrid data fusion of satellite navigation and positioning with wireless communications and cooperative positioning among mobile terminals.. The performance of the discussed positioning techniques are explored on the basis of already existing and operable terrestrial wireless communication systems such as GSM, UMTS, or LTE and it is shown how positioning issues are fixed in respective standards.Written by industry experts working at the cutting edge of technological development, the authors are well placed to give an excellent view on this topic, enabling in-depth coverage of current developments.Key features• Unique in its approach to dealing with a heterogeneous system approach, different cell structures and signal proposals for future communications systems• Covers hybrid positioning investigating how GNSS and wireless communications positioning complement each other• Applications and exploitation of positioning information are discussed to show the benefits of including this information in several parts of a wireless communications system

Since the principle of multi-carrier code division multiple access (MC-CDMA) was simultaneously proposed by Khaled Fazel et al. and Nathan Yee et al. at the IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC) in the year 1993, multi-carrier spread spectrum (MC-SS) has rapidly become one of the most wide spread independent research topics on the field of mobile radio communications. Therefore, the International Workshop on Multi-Carrier Spread Spectrum (MC-SS) was initiated in the year 1997. Multi-carrier and spread spectrum systems with their generic air interface and adaptive technologies are considered as potential candidates to fulfill the requirements of next generation mobile communications systems. The material summarized in this volume was selected for the 6th International Workshop on Multi-Carrier Spread Spectrum (MC-SS 2007) held in Herrsching, Germany from 07-09 May 2007. The workshop was organized by the Institute of Communications and Navigation of the German Aerospace Center (DLR) in Oberpfaffenhofen, Germany. During the workshop, many hot topics in the field of MC-SS were covered. First, several presentations regarding General Issues were given. Iterative Decoding strategies were also discussed. Furthermore, a special session was addressed on Interleave Multiple Division Access (IDMA). In the areas of Spectrum and Interference, Data Transmission, Adaptive Transmission, Multiple Antennas, Multi-Cell and Multi-Link, and Synchronization and Tracking new and innovative algorithms, strategies, and systems were proposed. Finally, a dominant hot topic during this workshop was the problem of Channel Estimation.

Therefore, the International Workshop on Multi-Carrier Spread Spectrum (MC-SS) was initiated in the year 1997 and renamed to the International Workshop on Multi-Carrier Systems & Solutions in 2009. The wireless standards 3GPP Long Term Evolution (LTE), WiMAX, IEEE 802.11a/n, and DxB have in common that they apply the spectrally ef?cient mul- carrier modulation in order to achieve very high rate data transmission. This trend is expected to continue in the future with the development of the next gene- tion of mobile wireless communications under the IMT-Advanced standardization activities. Additional measures like advanced coding, spreading, and MIMO are combined with multi-carrier transmission to further enhance the ef?ciency of future systems.The material summarized in this volume was selected for the seventh Int- national Workshop on Multi-Carrier Systems & Solutions (MC-SS 2009) held in Herrsching, Germany from 05-06 May 2009.
