Forward Error Correction for the Mathematically Challenged

This is worth looking at if, like me, you never found maths that easy. It is an article by Paul Nicholson on FEC, written so we can understand!

Paul is famous for his DX reception of amateur VLF and ULF signals. I am not sure if he is involved in VLF professionally. He certainly knows his stuff.
