POLAR ENCODING AND MODULATION METHOD AND APPARATUS, AND DEMODULATION AND DECODING METHOD AND APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18464337 titled 'POLAR ENCODING AND MODULATION METHOD AND APPARATUS, AND DEMODULATION AND DECODING METHOD AND APPARATUS

Simplified Explanation

The patent application describes an application that combines probability shaping technology with polar encoding and modulation methods, as well as demodulation and decoding methods.

  • The application combines probability shaping technology with a polar code to group and shape bit sequences before encoding and modulation.
  • Modulation and mapping are performed directly on the shaped bit sequences, while polar transformation is applied to some bit sequences along with other groups for modulation and mapping.
  • In the demodulation and decoding method, a modulation symbol sequence is decoded and a portion of the obtained bit sequence is directly mapped to obtain a second bit sequence.
  • The remaining part of the bit sequence is continuously decoded to obtain a first bit sequence.

Potential Applications

  • This technology can be applied in wireless communication systems, such as 5G networks, to improve the efficiency and reliability of data transmission.
  • It can be used in satellite communication systems to enhance the performance of data transmission over long distances.
  • The application can also find applications in IoT devices, where reliable and efficient communication is crucial.

Problems Solved

  • The combination of probability shaping technology with polar encoding and modulation methods solves the problem of inefficient data transmission in wireless communication systems.
  • It addresses the issue of error-prone communication over long distances in satellite communication systems.
  • The technology helps overcome the challenges of reliable and efficient communication in IoT devices.

Benefits

  • By combining probability shaping technology with polar encoding and modulation methods, the application improves the overall efficiency and reliability of data transmission.
  • It enables higher data rates and better error correction capabilities in wireless communication systems.
  • The technology enhances the performance of satellite communication systems by reducing errors and improving signal quality.

Original Abstract Submitted

This application provides a polar encoding and modulation method and apparatus, and a demodulation and decoding method and apparatus. In the polar encoding and modulation method, a probability shaping technology is combined with a polar code, to group to-be-encoded bit sequences, and probability shaping is performed on a group of bit sequences. Modulation and mapping are directly performed on all bit sequences obtained through probability shaping, and polar transformation is performed on some bit sequences obtained through probability shaping together with other groups of bit sequences for modulation and mapping. In the demodulation and decoding method, a modulation symbol sequence is demodulated and decoded, a part of obtained bit sequence is directly mapped to obtain a second bit sequence, and the other part is continuously decoded to obtain a first bit sequence.
