摘要:

We consider the class of two weight codes for the homogeneous metric of dual Hamming distance at least four. We characterize their weights.

When p is odd we show no such code exist. When p^k=4 we characterize these codes as inverse Gray images of Hadamard codes.

Joint work(s) with MinJia Shi, Zahra Sepasdar and Adel Alahmadi.
