این کتاب به بررسی دسترسی چندگانه تقسیم فرکانس تک حامل (SC-FDMA) می پردازد. با بررسی روند نوظهور ارتباطات مشارکتی و چگونگی بهبود امنیت لایه فیزیکی، طراحی طرحهای کدگذاری توزیع شده و پروتکلها را برای شبکههای رله بیسیم در نظر میگیرد که در آن کاربران برای ارسال دادههای خود به مقصد همکاری میکنند. این پروتکل تنوع همکاری را پیشنهاد می کند که فضا-زمان را اجرا می کند برای تعداد دلخواه گره های رله با پروتکل Amplify-and-Forward (AF) کدگذاری می کند. این طراحی یک کد فضایی-فرکانس توزیع شده (SFC) را برای کانالهای رله محو چند مسیره در نظر میگیرد که میتواند از تنوعهای همکاری و چند مسیره بهرهبرداری کند. همچنین طراحی طرحهای تنوع تعاونی برای سیستم SC-FDMA را در جهت پیوند بالا بررسی میکند. span>
''This book examines Single-Carrier Frequency Division Multiple Access (SC-FDMA). Exploring the emerging trend of cooperative communication and how it can improve the physical layer security, it considers the design of distributed coding schemes and protocols for wireless relay networks where users cooperate to send their data to the destination. It proposes a cooperative diversity protocol implementing space-time coding for an arbitrary number of relay nodes with Amplify-and-Forward (AF) protocol. It considers the design of a distributed Space-Frequency Code (SFC) for multipath fading relay channels that can exploit both cooperative and multipath diversities. It also investigates the design of cooperative diversity schemes for the SC-FDMA system in the uplink direction''-- Read more...
