When the alphabet size $q$ is even, we first propose a non-binary code correcting a burst of at most 2 deletions for $q$ -ary alphabets. Afterwards, we extend this result to the case where the length of the burst can be at most $t$ where $t$ is a constant. Finally, we consider...
They used to codes over larger alphabets and replaced the Hamming metric a metric generated by the convex body. For “superballs” {(x1,x2,…,xn)∈En:∑i=1nxiσ≤1} for the sequence dj = pjσ of dimensions, where pj is an odd prime their bound exceeds the Minkowski-Hlawka bound. ...
ASCII is a character encoding standard to provide a standard way for digital machines to encode characters. It is a mechanism to convert alphabets, digits, punctuation, and special characters into a special code (ASCII) that can understand (decode) by the digital systems. When it was developed...
Digital Displays − Binary codes are also used to display numbers and alphabets in digital systems. Barcode Systems − Binary codes are also used in barcode systems for product identification and inventory management. In this system, bars of different width and spaces between them represent binar...
For example, in part 2 of Example 2.2.1, the ordering simplifies the verification that all lowercase letters are present. The capital Greek letters Γ (pronounced “gamma”) and Σ (pronounced “sigma”) will often be used to denote alphabets. View chapter Book 1998, Fundamentals of the ...
Extended ASCII codes are used to represent letters from foreign alphabets and other symbols.When you type the letters of the alphabet on your keyboard, your computer converts them into binary numbers that it can understand. While this conversion would be annoying for humans to make every single ...
We give a polynomial time construction of binary codes with the best currently known trade-off between rate and error-correction radius. Specifically, we obtain linear codes over fixed alphabets that can be list decoded in polynomial time up to the so ca

binary to hexadecimal is by using a conversion table. We all know thatbinary numbersconsist of 0 and 1, which are known as bits. In contrast, hexadecimal is also a positional numeral system in which each hex digit represents 4 bits (binary digits) or numbers containing Alphabets from A to...
ASCII has 128 unique characters and among these characters, there are 95 printable characters and 33 non-printable characters. These include the alphabets, numbers, and punctuation marks and each alphabet or symbol uses a combination of binary strings. ...
