A Simple One-Sweep Algorithm for Optimal APP Symbol Decoding of Linear Block Codes

چکیده
Soft-input/soft-output symbol decoding plays a significant role in iterative decoding. We propose a simple optimal soft-input/softoutput symbol decoding algorithm for linear block codes which requires one forward recursion using a trellis. For many codes the decoding complexity is lower than previous methods, such as the algorithm by Bahl et al. [1], and the decrease is shown at its most when decoding Hamming codes.

متن کاملOn Full Diversity Space-Time Block Codes with Partial Interference Cancellation Group Decoding
In this paper, we propose a partial interferencecancellation (PIC) group decoding strategy/scheme for linear dis-persive space-time block codes (STBC) and a design criterion forthe codes to achieve full diversity when the PIC group decoding isused at the receiver. A PIC group decoding decodes the symbolsembedded in an STBC by dividing them into several groupsand decoding...

متن کاملAn Iterative Soft-Input Soft-Output Decoding Algorithm for Linear Block Codes
In this paper, reduced-complexity trellis-based soft-input soft-output (SISO) decoding of linear block codes is considered. A new low-weight subtrellis based SISO decoding algorithm for linear block code to achieve near optimal error performance with a significant reduction in decoding complexity is presented. The proposed scheme is suitable for iterative decoding of linear block codes when use...
