AI Technical Summary

Technical Problem

In existing constellation point modulation techniques, the lookup table method consumes a lot of storage resources, while the direct calculation method requires a lot of computing resources or time delay, making it difficult to achieve constellation point modulation efficiently.

Method used

By employing a coordinate index value determination unit and a coordinate value determination unit, the coordinate index value and coordinate value of the constellation point are determined through inversion and XOR operations, omitting lookup tables and multiplication-addition operations, and realizing constellation point modulation with less hardware resources and time delay.

Benefits of technology

It enables efficient constellation point modulation with less hardware resources and lower time latency, reducing the consumption of storage and computing resources.

Abstract

The present disclosure relates to an apparatus for constellation point modulation, comprising: a coordinate index value determination unit configured to determine coordinate index values of a constellation point according to an input binary sequence about information to be modulated, wherein an nth bit of the coordinate index values is determined according to an nth bit of the input binary sequence, an ith bit of the coordinate index values is determined by performing an exclusive OR operation and an inversion operation on the nth bit to the ith bit of the input binary sequence, i∈[1,n‑1], n is a number of binary bits contained in the input binary sequence, and the nth bit is a bit with the highest weight in the input binary sequence; and a coordinate value determination unit configured to determine coordinate values of the constellation point according to the coordinate index values. The apparatus can realize constellation point modulation with less hardware resources and smaller time delay.
