Data Transmission Method and Apparatus - A simplified explanation of the abstract
This abstract first appeared for US patent application 18166529 titled 'Data Transmission Method and Apparatus
Simplified Explanation
The patent application describes a method and apparatus for data transmission. Here is a simplified explanation of the abstract:
- The method at the transmit end involves obtaining a first sequence consisting of a first sub-sequence and a second sub-sequence.
- The first sub-sequence is mapped into K third sub-sequences based on a preset sequence group.
- The second sub-sequence undergoes differential coding and phase modulation to obtain a fourth sequence of length K'.
- K fifth sub-sequences are obtained based on the K third sub-sequences and the K' fourth sub-sequences.
- The second sequence, including the K fifth sub-sequences, is outputted.
At the receive end:
- The second sequence, including K fifth sub-sequences, is obtained.
- The K fifth sub-sequences are detected based on a preset sequence group to obtain a first sub-sequence.
- Differential demodulation is performed on the first sub-sequence to obtain a second sub-sequence, thereby determining the first sequence.
Potential applications of this technology:
- Wireless communication systems
- Data transmission in IoT devices
- Satellite communication
- Telecommunication networks
Problems solved by this technology:
- Efficient data transmission
- Improved signal quality and reliability
- Increased capacity for transmitting large amounts of data
Benefits of this technology:
- Enhanced data transmission speed
- Reduced transmission errors
- Increased network efficiency
- Improved overall performance of communication systems
Original Abstract Submitted
Embodiments of this application provide a data transmission method and apparatus. A method at a transmit end includes: obtaining a first sequence, where the first sequence includes a first sub-sequence and a second sub-sequence; mapping the first sub-sequence into K third sub-sequences based on a preset sequence group; performing differential coding and phase modulation on the second sub-sequence to obtain a fourth sequence whose length is K′; obtaining K fifth sub-sequences based on the K third sub-sequences and the K′ fourth sub-sequences; and outputting a second sequence including the K fifth sub-sequences. A method at a receive end includes: obtaining a second sequence including K fifth sub-sequences, and detecting the K fifth sub-sequences based on a preset sequence group to obtain a first sub-sequence; and performing differential demodulation based on the first sub-sequence to obtain a second sub-sequence, so that a first sequence is determined.
