Engineering Contradiction Analysis
1Reliability
If complex arithmetic operations are used for integrated interleaved encoding, then error correction capability is improved, but hardware complexity and latency increase
Solution Approach 1:
The patent replaces complex arithmetic operations (multiplication, division) with simpler operations (addition, subtraction, bit shifting) in the encoding process. This substitution maintains error correction capability while significantly reducing hardware complexity and computational latency.
Solution Approach 2:
The patent modifies the encoding parameters and mathematical operations used in integrated interleaved codes. By changing from general arithmetic operations to specific simplified operations (such as using addition instead of multiplication), the system achieves the same error correction performance with reduced hardware requirements.

AI summary
Integrated interleaved encoding is performed by obtaining a first piece of input data and a second piece of input data. The first piece of input data is systematically encoded using a first generator polynomial to obtain a first codeword. A second codeword is generated based at least in part on the second piece of input data and the first codeword. This includes by systematically encoding information based at least in part on the second piece of input data and the first codeword using a second generator polynomial. The first codeword and the second codeword are output.
