Notes on Reed-solomon Codes
Reed-Solomon codes are examples of error correcting codes, in which redundant information is added to data so that it can be recovered reliably despite errors in transmission or storage and retrieval. The error correction system used on CD’s and DVD’s is based on a Reed-Solomon code. These codes are also used on satellite links and other communications systems. We will first discuss the general...
متن کاملNotes 10 : List Decoding Reed - Solomon Codes and Concatenated codes
DRAFT Last class, we saw a toy version of recovering from a mixture of two Reed-Solomon codewords the two polynomials in question. Now we turn to list decoding arbitrary received words with a bounded distance from the Reed-Solomon code using Sudan’s [6] algorithm. This algorithm decodes close to a fraction 1 of errors for low rates. Then we will see an improvement by Guruswami and Sudan [4] whi...
متن کاملNotes 11 : List Decoding Folded Reed - Solomon Codes
We would like to recover a list of all polynomials f ∈ F[X] of degree k whose folded RS encoding (1) agrees with y in at least t columns, for some agreement parameter t. The goal would be to give an algorithm for as small a t as possible, as this corresponds to list decoding up to n − t errors. Note that we can solve this problem for t ≥ √ RN by simply unfolding the received word and using the ...
متن کاملStudies of Pacific Island Plants , XX Notes on Some Fijian
IN RECENT YEARS collections made by staff members of the Fiji Department of Agriculture have substantially added to the available study material of Fijian plants, permitting more adequate knowledge of many species and the recognition of others as new to science. Study of the Rubiaceae of these collections has made desirable the publication of notes to clarify certain complexes within the genus ...
متن کاملComment: Inter-Island referrals in Solomon Islands: a remote hospital perspective.
We thank Negin, Martiniuk, Farrell and Dalipanda for their contribution in Rural and Remote Health to the field of interisland referrals in the Solomon Islands. We agree that the provision of quality health services to people in remote areas is central to global efforts to achieve universal access to health care. We note with interest their findings that outline the increasing costs involved in...
