摘　　要：This paper focuses on the advanced Forward Error Correction(FEC) based on LowDensity Parity-Check(LDPC) codes for remote control and data transmission of Aeronautic and Astronautic Vehicles(AAV). It shows that the nontransparent LDPC codes with odd row weights are able to resist phase inversion with a small computational overhead. To the best of our knowledge, it is the first time to use FEC to resist phase inversion. Then, a high hardware-efficient FEC design for AAV, which is capable of correcting random errors as well as phase inversion, is proposed based on circulant decomposition with circulant size of 2s. Such a(4096, 2048) LDPC code has been adopted in a data transmission system due to its excellent error performance and hardware efficiency.This paper focuses on the advanced Forward Error Correction(FEC) based on LowDensity Parity-Check(LDPC) codes for remote control and data transmission of Aeronautic and Astronautic Vehicles(AAV).
