VARIABLE-TO-FIXED DISTRIBUTION MATCHING FOR PROBABILISTIC CONSTELLATION SHAPING IN WIRELESS COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18557037 titled 'VARIABLE-TO-FIXED DISTRIBUTION MATCHING FOR PROBABILISTIC CONSTELLATION SHAPING IN WIRELESS COMMUNICATIONS
The patent application describes methods, systems, and devices for wireless communications, specifically focusing on distribution matching and dematching procedures for a set of bits.
- Variable-to-fixed (v2f) distribution matching procedure is used to match input bits to output interim symbols, with a variable ratio between them.
- The process involves evaluating after each v2f distribution matching procedure to determine if additional bits require matching, and if so, deciding whether to perform another v2f matching procedure or an alternative one.
- Corresponding techniques for receiving devices are also discussed, including distribution dematching based on a v2f distribution dematching procedure.
Potential Applications: - This technology can be applied in wireless communication systems to optimize the distribution matching process for efficient data transmission. - It can enhance the performance of wireless networks by improving the handling of bits during transmission and reception.
Problems Solved: - Addresses the need for more efficient distribution matching and dematching procedures in wireless communications. - Improves the overall data transmission process by optimizing the allocation of bits to symbols.
Benefits: - Enhanced data transmission efficiency and reliability in wireless communication systems. - Improved performance and throughput of wireless networks. - Better utilization of resources for transmitting and receiving data.
Commercial Applications: - This technology can be utilized by telecommunications companies to enhance the efficiency of their wireless networks. - It can be integrated into wireless devices such as smartphones, tablets, and IoT devices to improve data transmission capabilities.
Questions about the technology: 1. How does the v2f distribution matching procedure improve the efficiency of data transmission in wireless communications? 2. What are the potential challenges in implementing this technology in existing wireless networks?
Frequently Updated Research: - Stay updated on the latest advancements in distribution matching and dematching procedures in wireless communications to ensure optimal performance and efficiency.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A transmitting device may perform distribution matching on at least a first subset of a set of bits, such as the bits of transport block. The distribution matching may include a variable-to-fixed (v2f) distribution matching procedure in which a ratio between a quantity of input bits to output interim symbols for the v2f distribution matching procedure is variable. The distribution matching include evaluating, after each instance of the v2f distribution matching procedure, whether additional bits remain for distribution matching, and if so, whether to perform an additional instance of the v2f distribution matching procedure or an alternative distribution matching procedure on the remaining bits. Corresponding techniques for a receiving device are also described, including distribution dematching techniques based on a v2f distribution dematching procedure.
