امروزه با گسترش روزافزون ارتباطات و شبکه های مخابراتی در تمام عرصه های زندگی بشر و نیاز مبرم به ارتباطات با نرخ و کیفیت بالا، تحقیقات بنیادی و کاربردی در زمینه ی علم و مهندسی مخابرات جزو اولویت های اصلی جوامع پیشرفته و در حال توسعه است. بنا به ضرورت مذکور در این پایان نامه به بررسی تحقیقات انجام -شده در زمینه تئوری اطلاعات شبکه های مخابراتی خصوصا شبکه های رله در تئوری اطلاعات که بسیار مورد توجه...

Data Forwarding in Wireless Relay Networks

Broadband wireless communication has brought users a number of multimedia services for years. As wireless broadband markets mature, system operators face new problems. First, system capacity is bounded by finite radio resources. Second, service providers increasing spend on network deployments and services provisions. With limited radio resource and increased costs, operators have no choice but...

Mobile-relay Forwarding in Opportunistic Networks

Sphere-based list Forwarding Strategy for MIMO Relay Networks

A sphere-based list forwarding scheme for multipleinput multiple-output (MIMO) relay networks is proposed and analysed. Firstly, an estimate forwarding (EF) methods is proposed, which forwards the minimum mean squared error (MMSE) estimate of the source data to the destination. Since it performs like amplify-and-forward (AF) and decode-and-forward (DF) for the low and high signal-to-noise ratio...

Low-density Parity-check Codes for Wireless Relay Networks

In wireless networks, it has always been a challenge to satisfy high traffic throughput demands, due to limited spectrum resources. In past decades, various techniques, including cooperative communications, have been developed to achieve higher communication rates. This thesis addresses the challenges imposed by cooperative wireless networks, in particular focusing on practical code constructio...
