This paper proposes an importance sampling design for the codeword error rate estimation of low-density parity-check codes. An error set partitioning method is introduced to reduce the error boundary complexity and to improve the simulation efficiency. This is a follow-up to the work in (B. ...
It is proved that if the modulator-channel combination satisfies a particular symmetry condition, the codeword error rate performance is independent of the transmitted codeword. It is shown that this result holds for both linear-programming decoders and sum-product decoders. In particular, this ...
COFDM is a special case of multicarrier transmission, where a single DataStream is transmitted over number of lower rate subcarrier. In case of coded OFDM the information in the lost carrier can be recovered provided enough forward error correction is sent. Main reason to use COFDM is to incre...
Bit [4]: Set for high symbol error rate. This can be the entire number of codewords in the traffic. Bit [5]: Set for correctable codeword errors. Bit [6]: Set for uncorrected codeword errors. Bit [15:8]: Each bit is set when 15 to 8 symbols are corrected in a codeword (LSB...
We prove that for any $mathbb {F}_{q}$ -symmetric memoryless channel, any code length, and any code dimension, all the codeword symbols in such polar codes have the same symbol error rate (SER) under the successive cancellation (SC) decoder. 展开 ...
A method for improving the code rate and error correction capability of a cyclic code Currently, there has been an increasing demand for operational and trustworthy digital data transmission and storage systems. This demand has been augmente... T Shah,AAD Andrade - 《Computational & Applied Mathema...
It is shown that the proposed two step decoding scheme shows better performance than a bit flipping based scheme and reduces the complexity by about 0.013 for 4 signal streams with the cost of bit error rate degradation within 0.5dB. 展开 ...
While this appears to be a minor change, it can have a significant impact on the percentage error, depending on the variables in the denominator of the equation. The same formula applies for correctable codeword errors. While a correctable error rate of over 5% seems high, it is important ...
Post-manufacturing, 17-times acceptable raw bit error rate enhancement, dynamic codeword transition ECC scheme for highly reliable solid-state drives, SSDs A dynamic codeword transition ECC scheme is proposed for highly reliable solid-state drives, SSDs. By monitoring the error number or the write...
