Introduction to Wireless Systems

A Coherent Systems View of Wireless and Cellular Network Design and Implementation

Written for senior-level undergraduates, first-year graduate students, and junior technical professionals, Introduction to Wireless Systems offers a coherent systems view of the crucial lower layers of today’s cellular systems. The authors introduce today’s most important propagation issues, modulation techniques, and access schemes, illuminating theory with real-world examples from modern cellular systems. They demonstrate how elements within today’s wireless systems interrelate, clarify the trade-offs associated with delivering high-quality service at acceptable cost, and demonstrate how systems are designed and implemented by teams of complementary specialists.

Coverage includes

• Understanding the challenge of moving information wirelessly between two points
• Explaining how system and subsystem designers work together to analyze, plan, and implement optimized wireless systems
• Designing for quality reception: using the free-space range equation, and accounting for thermal noise
• Understanding terrestrial channels and their impairments, including shadowing and multipath reception
• Reusing frequencies to provide service over wide areas to large subscriber bases
• Using modulation: frequency efficiency, power efficiency, BER, bandwidth, adjacent-channel interference, and spread-spectrum modulation
• Implementing multiple access methods, including FDMA, TDMA, and CDMA
• Designing systems for today’s most common forms of traffic—both “bursty” and “streaming”
• Maximizing capacity via linear predictive coding and other speech compression techniques
• Setting up connections that support reliable communication among users

Introduction to Wireless Systems brings together the theoretical and practical knowledge readers need to participate effectively in the planning, design, or implementation of virtually any wireless system.

《無線和蜂窩網絡設計和實施的一致系統視角》

《無線系統導論》針對高年級本科生、一年級研究生和初級技術專業人員，提供了對當今蜂窩系統關鍵底層的一致系統視角。作者介紹了當今最重要的傳播問題、調製技術和接入方案，並通過現代蜂窩系統的實際例子來闡明理論。他們展示了當今無線系統中的各個元素相互關聯，澄清了在可接受的成本下提供高質量服務的權衡，並展示了如何由互補專業團隊設計和實施系統。

內容包括：
- 理解在兩點之間無線傳輸信息的挑戰
- 解釋系統和子系統設計師如何共同分析、規劃和實施優化的無線系統
- 設計以獲得質量接收：使用自由空間範圍方程，並考慮熱噪聲
- 理解地面通道及其損壞，包括陰影和多徑接收
- 重複使用頻率以在廣大的用戶基礎上提供廣域服務
- 使用調製：頻率效率、功率效率、BER、帶寬、鄰信道干擾和展頻調製
- 實施多重接入方法，包括FDMA、TDMA和CDMA
- 為當今最常見的流量形式（“突發”和“流式”）設計系統
- 通過線性預測編碼和其他語音壓縮技術來最大化容量
- 建立支持用戶之間可靠通信的連接

《無線系統導論》將讀者所需的理論和實踐知識集合在一起，使其能夠有效參與幾乎任何無線系統的規劃、設計或實施。
