This Brief introduces the wireless spectrum market and discusses the current research for spectrum auctions. It covers the unique properties of spectrum auction, such as interference relationship, reusability, divisibility, composite effect and marginal effect, while also proposing how to build economic incentives into the network architecture and protocols in order to optimize the efficiency of wireless systems.Three scenarios for designing new auctions are demonstrated. First, a truthful double auction scheme for spectrum trading considering both the heterogeneous propagation properties of channels and spatial reuse is proposed. In the second scenario, a framework is designed to enable spectrum group secondary users with a limited budget. Finally, a flexible auction is created enabling operators to purchase the right amounts of spectrum at the right prices according to their users’ dynamic demands.Both concise and comprehensive, Auction Design for the Wireless Spectrum Market is suited for professionals and researchers working with wireless communications and networks. It is also a useful tool for advanced-level students interested in spectrum and networking issues.

This book offers a compelling archaeological exploration of China’s millennia-old civilization. Centering on 15 iconic cultural relics—from the Jiahu bone flute (a witness to early Chinese music systems) and Liangzhu jade cong (a symbol of prehistoric religious hierarchy) to the Four-Sheep Square Zun (a masterpiece of Shang Dynasty bronze craftsmanship) and the astronomical lacquer box from the Marquis Yi of Zeng’s tomb—the book weaves together material evidence with classical texts like The Rites of Zhou. By integrating archaeology, history, astronomy, metallurgy, and ritual studies, Peng Lin illuminates the technical ingenuity, cultural traditions, and social structures of ancient China, while highlighting the “pluralistic integration” of Chinese civilization’s evolution.More than a relic showcase, this work pioneers an interdisciplinary approach that bridges archaeological findings and textual research, debunking one-sided interpretations of ancient history. A staple in university liberal arts curricula, it provides both scholars and general readers with a rigorous yet accessible lens to understand how material culture shapes the narrative of China’s past. It is an indispensable guide for anyone seeking to grasp the profound connections between relics, culture, and the origins of Chinese civilization.
