Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a transmitter and receiver system, along with methods, for improved signal transmission and detection using specially structured 'pilot sequences.' The pilot sequence is generated by repeating a base sequence in a certain pattern, which makes it easier and more reliable for the receiver to detect, synchronize, and interpret transmitted data, even when there are distortions such as frequency offsets or asynchronous timing. The system is particularly designed to minimize computational effort during detection and improve robustness against noise and signal misalignments.

Use CasesContent extracted from patent full text and abstract with AI.

  • Wireless sensor networks for the Internet of Things (IoT) where devices transmit data infrequently and asynchronously.
  • Low-power telemetry systems (e.g., remote environmental sensors) that need reliable data transmission with minimal energy and computational resources.
  • Industrial automation systems where many devices may send short, unsynchronized data packets over shared radio channels.
  • Battery-powered communication devices that benefit from efficient, low-energy signal processing methods.
  • Radio-based communication systems that operate in challenging environments with interference or frequency drift (e.g., mobile or satellite communications).

BenefitsContent extracted from patent full text and abstract with AI.

  • Reduces computational effort in signal detection and synchronization, allowing use in low-power, resource-constrained devices.
  • Improves the accuracy and reliability of packet detection, timing, and frequency synchronization, even in the presence of noise and frequency offset.
  • Enables efficient operation in asynchronous transmission environments where sender and receiver are not time-synchronized.
  • Customizable pilot sequence structures allow adaptation for different modulation methods and system requirements.
  • Can be implemented in both hardware and software, making it suitable for a wide range of platforms and applications.

Patent Abstract

The invention relates to a transmitter (1) which is configured in such a way that it transmits signals having a respective pilot sequence with multiple pilot sequence symbols, wherein the transmitter (1) has a signal generator (2), wherein the signal generator (2) is configured in such a way that it provides the pilot sequence based on a basic sequence having multiple basic sequence symbols, wherein the signal generator (2) provides the pilot sequence symbols based on the basic sequence symbol that is successively repeated (R-1) times, and wherein R is a natural number greater than or equal to two, wherein the basic sequence is configured in such a way that a correlation of the pilot sequence with a transmission signal formed by the pilot sequence has a primary maximum that is as narrow as possible and/or secondary maximums that are as small as possible.
