Parallel Bit Interleaver for Low-Latency Wireless Packet Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current FLO transmission technologies are inefficient as they process bits serially, one per clock edge, which is resource-intensive and results in significant inefficiency, especially for packets with hundreds of bits.
Innovation Solution
Implementing a parallel bit interleaver that processes multiple bits per clock event, such as two, four, or eight bits, and stores them in an interleaving memory, allowing for reduced latency and increased throughput by enabling dynamic processing adjustments based on packet size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If serial bit processing is used (one bit per clock edge), then device complexity is reduced, but productivity deteriorates significantly
Solution Approach 1:
The patent segments the bit processing into parallel channels, where multiple bits are processed simultaneously in separate processing paths. Each processing path handles a specific number of bits in parallel, effectively dividing the overall processing task into manageable segments that can be executed concurrently, thereby increasing throughput without proportionally increasing device complexity.
Solution Approach 2:
The patent transitions from one-dimensional serial processing to multi-dimensional parallel processing by introducing additional processing dimensions. Multiple bits are mapped to different processing paths and clock edges simultaneously, creating a multi-dimensional processing structure that increases throughput while managing complexity through structured organization.
2Loss of time
If serial bit mapping is employed, then ease of operation is maintained, but loss of time increases due to processing delays
Solution Approach 1:
The patent applies preliminary action by pre-mapping multiple bits to different processing paths and clock edges before actual transmission. The parallel bit interleaver pre-processes the data by distributing bits across multiple paths in advance, reducing the overall processing time and latency while maintaining operational simplicity through structured pre-arrangement.
3Productivity
If parallel bit processing is implemented, then productivity increases, but device complexity increases
Solution Approach 1:
The parallel bit interleaver is segmented into multiple independent processing paths, each handling a specific subset of bits. This segmentation allows the complex parallel processing task to be divided into simpler, manageable units that can be implemented using standard processing elements, thereby increasing throughput while controlling the complexity growth.
4Adaptability or versatility
If dynamic processing adjustments are made based on packet size, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent implements dynamic processing by allowing the parallel bit interleaver to adjust its operation based on the actual packet size. The system can dynamically select the appropriate number of parallel paths and clock edges to use, optimizing processing efficiency for different packet sizes while maintaining a manageable level of complexity through structured control mechanisms.
Data Source
AI summary
Systems and methods are provided to process wireless data packets. A method includes determining a subset of data bits to be processed at a wireless transmitter and employing a clock edge to store the data. The clock edge allows parallel mapping of at least two bits from the subset of data bits into an interleaver memory per a given clock edge. From the memory, other encoding and scrambling processes are applied before transmitting the data packets across a wireless network.
