LTE Relay Forwarding Algorithms: AF and DF Algorithms with Performance Analysis

LTE Relay Forwarding Algorithm Program: AF and DF Algorithms with Performance Diagrams

In LTE relay forwarding algorithms, AF (Amplify-and-Forward) and DF (Decode-and-Forward) algorithms are widely implemented. The AF algorithm enhances LTE relay system performance by improving signal transmission quality and expanding coverage range through signal amplification techniques. In code implementation, this typically involves real-time signal gain adjustment using digital signal processing modules. The DF algorithm employs spatial diversity technology by utilizing multiple antennas for signal reception and transmission, thereby increasing system reliability and anti-interference capability. From a programming perspective, DF implementations often include error correction coding/decoding modules and MIMO (Multiple-Input Multiple-Output) processing functions.

These algorithms enable LTE relay systems to achieve higher data transmission rates and more reliable communication connections. The performance diagrams demonstrate signal quality improvements and coverage expansion under various scenarios. Key implementation aspects include adaptive modulation coding selection and channel state information feedback mechanisms. The application of these algorithms provides effective solutions for performance enhancement and optimization of LTE relay systems, where algorithm selection often depends on channel conditions and quality-of-service requirements through configurable threshold parameters in the system configuration.
