GSM/GPRS Receiver Burst Skipping for Lower-Power Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional GSM/GPRS receivers are power-consumptive as they need to remain on to receive entire encoded data blocks for decoding, which is inefficient and consumes more energy, especially in idle or repetitive data scenarios.
Innovation Solution
The solution allows decoding and detection of encoded data blocks in GSM/GPRS receivers by receiving only a portion of the data block, leveraging good signal conditions and repetitive data patterns to skip unnecessary bursts, thereby reducing receiver on-time and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiver remains on to receive the entire encoded data block, then the decoding accuracy is improved, but the power consumption increases
Solution Approach 1:
The patent applies partial action by attempting to decode the data block after receiving only a portion of the encoded bursts rather than waiting for the complete block. The receiver processes available data incrementally, using partial decoding attempts with increasing portions of the received data until successful decoding is achieved or all bursts are received.
Solution Approach 2:
The patent employs preliminary action through early decoding attempts made as soon as a minimum threshold of bursts is received. The system performs preliminary decoding operations before the complete data block is received, allowing potential early termination and avoiding the need to receive all bursts in every case.
2Use of energy by moving object
If the receiver processes only a portion of the encoded data block, then the power consumption is reduced, but the risk of incomplete or erroneous decoding increases
Solution Approach 1:
The patent applies dynamics by making the decoding process adaptive and dynamic rather than static. The receiver continuously assesses decoding success after each burst reception and dynamically adjusts whether to continue receiving or terminate early. This dynamic approach allows the system to optimize between power consumption and reliability based on real-time decoding outcomes.
Solution Approach 2:
The patent employs feedback mechanisms where the receiver evaluates decoding results after processing each received burst and uses this feedback to determine whether to continue receiving additional bursts or terminate the reception early. This feedback-driven decision-making ensures that decoding accuracy requirements are met while minimizing unnecessary power consumption.
3Reliability
If the receiver waits for all bursts to be received before decoding, then the decoding reliability is improved, but the receiver on-time increases
Solution Approach 1:
The patent reduces receiver on-time by implementing partial action decoding, where the receiver attempts to decode the data block after receiving only a portion of the encoded bursts rather than waiting for all bursts to be completely received before initiating any decoding operations.
Solution Approach 2:
The patent applies preliminary action by initiating decoding operations as soon as a minimum threshold of bursts is received, performing preliminary decoding attempts before the complete data block arrives, thereby reducing the total duration the receiver must remain active.
4Duration of action of moving object
If the receiver attempts early decoding with partial data, then the receiver on-time is reduced, but the complexity of the decoding process increases
Solution Approach 1:
The patent applies segmentation by dividing the decoding process into multiple stages corresponding to different portions of received bursts. The decoding is segmented into incremental attempts where each stage processes available data independently, allowing the receiver to terminate early if successful or continue if more data arrives, thereby managing complexity through structured segmentation.
Data Source
AI summary
Apparatus, and an associated method, for recovering the informational content of an encoded data block. Data bursts are delivered to a receiver. A series of data bursts together include all of the informational content of the encoded data block. A detector detects delivery to the receiver of the data bursts. A determiner determines indicia associated with the communicated data. And, responsive thereto, the data is decoded, selectably utilizing fewer than all of the data bursts that form the encoded data block.
