摘要：For a given prime power q, a new method for constructing q-ary constant weight codes is presented, and then several classes of q-ary constant weight codes are given by using the trace map over finite fields. Especially, for q = 2, some of these codes are optimal, and then the maximal possible sizes of two classes of binary constant weight codes are determined, respectively。
