Linear-Time List Decoding in Error-Free Settings: (Extended Abstract)

This paper is motivated by the program of constructing list-decodable codes with linear-time encoding and decoding algorithms with rate comparable to or even matching the rate achieved by the best constructions with polynomial encoding/decoding complexity. We achieve this for three basic settings of list decoding, and view these as the first promising steps in the above general program.
