A Reed-Solomon code is specified as RS (n, These aligned symbols are then passed through a Reed-Solomon encoder. 16}, and its application to the reliable delivery of data objects A FEC group consists of n data and k check packets where n+k <= 2m. In information theory and coding theory, Reed–Solomon codes are a group of error-correcting codes that were introduced by Irving S. It can run in platform of MIPS/ARM/i386/x64 of linux, especially for some embedded projects. We will address the VHDL implementation of an RS This video presents a bird's eye view of how Reed The newer Ethernet Reed-Solomon FEC does something similar, but with an even larger block size.
