SEQUENCE-BASED SIGNAL PROCESSING METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17940824 titled 'SEQUENCE-BASED SIGNAL PROCESSING METHOD AND APPARATUS
Simplified Explanation
The abstract describes a method and apparatus for sequence-based signal processing. Here are the key points:
- The invention provides a method for determining a sequence to be used for sending a signal using a physical uplink control channel (PUCCH).
- The determined sequence meets a preset condition, ensuring low sequence correlation and maintaining a relatively small peak-to-average power ratio (PAPR) value and cubic metric (CM) value.
- The N elements in the determined sequence are mapped to N subcarriers to generate a first signal.
- The first signal is then sent, meeting the requirements of a communication application environment where a signal is sent using a PUCCH.
Potential applications of this technology:
- Wireless communication systems
- Cellular networks
- Internet of Things (IoT) devices
- Satellite communication systems
Problems solved by this technology:
- Maintains low sequence correlation, ensuring reliable signal transmission
- Reduces peak-to-average power ratio (PAPR) and cubic metric (CM) values, improving power efficiency and reducing interference
- Meets the requirements of communication applications using a physical uplink control channel (PUCCH)
Benefits of this technology:
- Improved signal transmission reliability
- Enhanced power efficiency
- Reduced interference
- Compatibility with communication applications using a PUCCH
Original Abstract Submitted
A sequence-based signal processing method and apparatus are provided. A sequence meeting a requirement for sending a signal by using a physical uplink control channel (PUCCH) is determined, where the sequence is a sequence {f} consisting of N elements, fis an element in the sequence {f}, and the determined sequence {f} is a sequence meeting a preset condition; then, the N elements in the sequence {f} are respectively mapped to N subcarriers to generate a first signal; and the first signal is sent. By using the determined sequence, when a signal is sent by using a PUCCH, a low sequence correlation can be maintained, and a relatively small peak-to-average power ratio (PAPR) value and cubic metric (CM) value can also be maintained, thereby meeting a requirement of a communication application environment in which a signal is sent by using a PUCCH.
