Data modulation method and device, data demodulation method and device, service node, terminal, and medium

Abstract

Provided are a data modulation method and device, a data demodulation method and device, a service node, a terminal, and a medium. The data modulation method is applied to the service node, and the data modulation method includes that: a modulation parameter A is determined according to a modulation manner of data; and the data is modulated according to a target constellation point symbol, where the target constellation point symbol is a product of A and X, and X is an initial constellation point symbol corresponding to the modulation manner.
