Is it possible to find the error location polynomial in t cycles for Reed–Solomon Code using a modified RiBM algorithm?
Recently I've read a paper on Reed–Solomon Code, in the decoding part, the author proposed a modified RiBM algorithm which use t cycles(while RiBM algorithm needs 2t cycles) to find the error location ...

Where do single-bit shift errors commonly occur in real-world systems?
I'm interested in understanding the prevalence of single-bit shift errors—situations where a bit moves to an adjacent position without any insertion or deletion of bits—in practical systems. For ...

How to accomodate feedback bits from Base Station to devices in LTE or 5g?
I am trying to think of a way in which the base station (BS) can send say 100 bits of feedback to devices in my cell. My confusion is what is a good way to send this feedback bits. This is during the ...

Why can interleaving make the channel "memoryless"?
I'm trying to understand "interleaving" from a theoretical point of view. This paper claimed that by sufficient long interleaving, the channel can be treated as memoryless. Does this holds ...
