Multi-Block Radio Transmission for Burst Interference Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intermittent interference sources in radio communication systems cause loss of transmitted packets due to bursty noise, leading to synchronization and payload data loss, and existing methods like interleaving and splitting packets into smaller blocks are inefficient in handling such interference.
Innovation Solution
A multi-block transmission system where each block includes a synchronization portion and control information, with pre-negotiation of timing and control information through multi-block request and response packets, allowing for parallel decoding and reduced overhead.

Engineering Contradiction Analysis
1Loss of energy
If data is transmitted as a single block packet, then transmission overhead is minimized, but the loss of synchronization information and payload data occurs due to bursty noise interference
Solution Approach 1:
The invention divides a data packet into multiple blocks, where each block contains a portion of the payload and associated synchronization information. This segmentation allows the receiver to successfully decode individual blocks even when bursty noise interferes with only part of the transmission, thereby improving reliability without excessive overhead.
Solution Approach 2:
The invention embeds synchronization information at the beginning of each block before the payload data. This preliminary action ensures that the receiver can establish synchronization for each block independently, allowing successful decoding even if interference occurs during payload transmission.
2Reliability
If the payload of one packet is split into multiple smaller blocks with checksum, then collision loss in the presence of bursty noise sources is reduced, but critical information may be corrupted leading to complete loss of receiver's ability to decode any blocks
Solution Approach 1:
The invention segments the payload into multiple blocks, with each block containing its own synchronization information and checksum. This segmentation ensures that corruption in one block does not propagate to other blocks, as each block is independently decodable.
Solution Approach 2:
The invention applies different functions to different parts of each block: synchronization information at the beginning for timing recovery, checksum for error detection, and payload data for information transfer. This local differentiation ensures that even if part of a block is corrupted, the receiver can identify and handle the corruption locally without losing the entire packet.
3Reliability
If interleaved data packets are used to improve robustness, then data can be reconstructed if some interference has occurred, but the receiver needs to wait until the whole data packet has been received before reconstructing, increasing latency
Solution Approach 1:
The invention divides the packet into independent blocks that can be decoded individually as they are received. Each block contains sufficient synchronization and checksum information to be processed independently, eliminating the need to wait for the entire packet before beginning reconstruction.
Solution Approach 2:
The invention places synchronization information at the start of each block, allowing the receiver to begin processing and reconstruction of each block immediately upon receipt, rather than waiting for the complete packet. This preliminary synchronization enables parallel processing of multiple blocks.
Data Source
AI summary
A radio communication system, comprising a transmitter and a receiver wherein the transmitter is configured to transmit a multi-block request including control and timing information relating to a subsequent multi-block transmission, the receiver is configured to receive and decode said multi-block request, the transmitter is configured to subsequently transmit the multi-block transmission, wherein the multi-block transmission comprises a series of discrete blocks. Each block comprises a respective data payload and a synchronisation portion, and each synchronisation portion enables synchronisation between the transmitter and receiver when used in combination with the control and timing information, independently of receipt of other blocks in the multi-block transmission.
