OFDM (Orthogonal frequency division multiplexing} has been shown to be an effective technique to combat multipath fading in wireless channels. It is being used in various wireless communication systems such as in Digital Audio Broadcasting (DAB) and Video Broadcasting (DVB) in Europe and many of IEEE 802.11 and IEEE 802.16 standards. This book provides a comprehensive introduction to the theory and practice of OFDM for wireless communications. It includes basic concepts of OFDM, performance optimization, time- and frequency-offset estimation, channel estimation, peak-to-average power ratio reduction, and MIMO OFDM techniques. The key concepts are developed with detailed derivations and proofs to make the material accessible and easy to follow by both students and professionals. While chapters have been written by experts in their respective subject area, the authors have tried to make symbols, notations, presentations and styles consistent. To facilitate readers, the material includes extensive references as well as a large and useful index at the end of the book. OFDM for Wireless Communications is highly recommended for graduate level courses in advanced digital communication and professional seminars and tutorials on wireless OFDM.

We develop a dynamic asset-pricing model of cryptocurrencies/tokens that allow users to conduct peer-to-peer transactions on digital platforms. The equilibrium value of tokens is determined by aggregating heterogeneous users' transactional demand rather than discounting cashflows as in standard valuation models. Endogenous platform adoption builds upon user network externality and exhibits an S-curve - it starts slow, becomes volatile, and eventually tapers off. Introducing tokens lowers users' transaction costs on the platform by allowing users to capitalize on platform growth. The resulting intertemporal feedback between user adoption and token price accelerates adoption and dampens user-base volatility.
