Interleaving for Transmission of Telegrams with Variable Subpacket Count and Successive Decoding

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

This patent describes a wireless data transmission method and system that splits messages into core data (important for initial processing) and extension data (additional information). Both are encoded and distributed (interleaved) into multiple sub-packets, which are sent with time and frequency hopping to reduce the effects of interference. The core data is structured so that it can be decoded and used even if some sub-packets are lost, providing essential information for receiving or decoding the rest of the message. The method ensures higher reliability, supports variable message lengths, and enables partial decoding before the complete message is received.

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

• Wireless sensor networks with intermittent or interference-prone connections
• Telemetry systems where data reliability is critical, such as remote monitoring or control systems
• Industrial IoT (Internet of Things) devices needing robust, low-power wireless communication
• Smart metering where messages must be reliably received despite channel noise or packet losses
• Wireless communication in hostile radio environments (e.g., factories, urban areas, or military applications)
• Battery-powered devices that need efficient, reliable data transfer with minimal retransmissions

BenefitsContent extracted from patent full text and abstract with AI.

• Greater reliability of data transmission, even if some packets are lost due to interference
• Ability to decode essential (core) information before all sub-packets are received, enabling faster or partial processing
• Support for messages of variable length, improving flexibility for different applications
• Improved error protection, especially for short messages, through combined channel coding
• Optimized placement of critical data within packets (near synchronization sequences) for higher decoding accuracy
• Reduced need for retransmissions, saving power and bandwidth, which is especially important for low-power or battery-operated devices
• Increased robustness to interference by using time and frequency hopping patterns for packet transmission

Patent Abstract

Exemplary embodiments provide a transmission method for the wireless transmission of data in a communications system (e.g. a sensor network or telemetry system). The data comprises core data and additional data, the core data being split in encoded and interleaved form into a plurality of core data sub-packets and the additional data being split in encoded and interleaved form into a plurality of additional data sub-packets, wherein at least some of the core data contained in the core data sub-packets is required for the receipt of the additional data or additional data packets.
