Last month, I introduced an 8-PSK example. As I showed, the 8-PSK example appears to be the combination of coding and modulation that's the basis for Trellis-coded modulation (TCM). However, it's not ...

In this paper, we present a new concept and its circuit implementation for high-speed associative memories based on Hamming distance. A chained search logic embedded in a memory cell enables a ...

It seems like only yesterday we covered a project using QR codes to archive data on paper (OK, it was last Thursday), so here’s another way to do it, this time with a dedicated codec using the full ...

You may not know the name [Richard Hamming], but you definitely use some of his work. While working for Bell Labs, he developed Hamming codes — the parent of a class of codes that detect, and ...
