This paper provides analysis of high performance forward error control (FEC) coding scheme suitable for next generation HF-IP systems, which can be used as an optional scheme according to the requirements of the application. Present HF-IP systems comply with NATO STANAG 4539 Physical layer standards which use convolutional encoding for forward error protection and correction. The FEC that has been proposed in this paper is a class of quasi cyclic Low Density Parity Check (LDPC) coding scheme suitable for HFIP systems. Additive groups of Finite Fields have been used to construct short-length structured LDPC codes with 4 different rates suitable for different HF channel conditions. The codes have been simulated with ITU-R F1487 HF channel model [1] for performance analysis with different conditions and latitudes.
