Description

The Software Communications Architecture (SCA) establishes an implementation-independent framework for the development of Joint Tactical Radio System software configurable radios. It specifies the Operating Environment, services and interfaces that applications use.

Software Defined Radio: The Software Communications Architecture focuses on the issues and benefits associated with developing a radio system in compliance with the SCA specification. This book provides a comprehensive, practical introduction to building a SCA-compliant system taking the reader through the historical and conceptual background to help filling in the gaps between the intent of the SCA specification and the practice.

Key features:

  • Presents a practical approach to the Software Communications Architecture
  • Provides an example-oriented understanding of the usage of the SCA and thus allows the reader to extend the concepts and practice to more complicated multi-processor distributed environments.
  • Covers the Operating Environment: a Core framework, CORBA middleware, POSIX operating systems and Domain profiles.
  • Features an accompanying website with appendices, and links to further information on the SCA.

This invaluable reference will provide applications programmers, designers, professional researchers, wireless manufacturers and operators with an indispensable guide to the Software Communications Architecture. Advanced undergraduate and postgraduate students on mobile and wireless communications courses will also find this to be an excellent guide to the topic.

描述

軟體通訊架構(SCA)建立了一個與實現無關的框架,用於開發聯合戰術無線電系統軟體可配置無線電。它指定應用程序使用的操作環境、服務和接口。

《軟體定義無線電:軟體通訊架構》專注於開發符合SCA規範的無線電系統所涉及的問題和好處。本書提供了一個全面而實用的介紹,引導讀者了解構建符合SCA規範的系統的歷史和概念背景,以幫助填補SCA規範意圖和實踐之間的差距。

主要特點:
- 提供了一種實用的軟體通訊架構方法
- 提供了以實例為導向的對SCA使用的理解,從而使讀者能夠將概念和實踐擴展到更複雜的多處理器分佈式環境中
- 詳細介紹了操作環境:核心框架、CORBA中間件、POSIX操作系統和域配置文件
- 附帶網站,包含附錄和有關SCA的進一步信息的鏈接

這本寶貴的參考資料將為應用程序開發人員、設計師、專業研究人員、無線電製造商和運營商提供對軟體通訊架構的不可或缺的指南。移動和無線通訊課程的高年級本科生和研究生也會發現這是一個優秀的主題指南。
