,Codes over ℤ4,In 1994 it was shown (see [88], which we use as guideline for this chapter) that several well known good binary codes can be constructed by first constructing a code over the alphabet ℤ. and then mapping the coordinates to ℤ.. We first study codes over ℤ. in general.

Goppa Codes,Consider once again the parity check matrix of a (narrow sense) BCH code as given in the proof of Theorem 6.6.2, i.e..where . is a primitive nth root of unity in F., and each entry is interpreted as a column vector of length . over F.; existence of . implies that .∣(. — 1).
