Lattice Reduction-Based THP Precoding

Lattice reduction-based THP precoding utilizes lattice reduction techniques under the zero-forcing criterion to significantly enhance communication system performance. This technology leverages the concept of lattice reduction by applying precoding to transmission signals, thereby reducing bit error rates and power consumption during transmission. Through the zero-forcing criterion, we can more effectively select appropriate lattice reduction techniques and implement them in communication systems. From an implementation perspective, the algorithm typically involves: - Lattice basis reduction using techniques like LLL (Lenstra-Lenstra-Lovász) algorithm - QR decomposition for channel matrix preprocessing - Modular arithmetic operations for THP signal mapping - Zero-forcing equalization to cancel interference The application of this technology can bring higher transmission rates and more reliable signal transmission to wireless communication fields. Key functional components include lattice reduction modules, precoding filters, and interference cancellation units. Therefore, lattice reduction-based THP precoding holds significant application value in communication systems, particularly for MIMO configurations where it improves system capacity and error performance through optimized signal constellation design.
