3 Claims

1. A modulation method, comprising:

modulating data by using a non-uniform constellation to generate modulated data, wherein the non-uniform constellation is a constellation in which constellation points are not uniformly spaced; and

sending the modulated data,

wherein, when the non-uniform constellation is a 1024-point constellation, coordinates of constellation points of the 1024-point constellation on a real axis are as follows:
