The [1,0]-twisted generalized Reed-Solomon code

In this paper, we not only give the parity check matrix of the [1, 0]-twisted generalized Reed-Solomon (in short, TGRS) code, but also determine the weight distribution. Especially, we show that the [1, 0]-TGRS code is not GRS or EGRS. Furthermore, we present a sufficient and necessary condition for any punctured code of the [1, 0]-TGRS code to be self-orthogonal, and then construct several classes of self-dual or almost self-dual [1, 0]-TGRS codes. Finally, on the basis of these self-dual or almost self-dual [1, 0]-TGRS codes, we obtain some LCD [1, 0]-TGRS codes.
