56128 基于概率计算的Chase算法可以在保证译码性能的情况下,大幅度降低软译码的复杂度,使得RS软译码算法得到实际应用. The Chase algorithm based on stochastic computing can significantly reduce the complexity of softdecoding while ensuring the decoding performance, so that the soft decoding algorithm of Reed-Solomon codes ispractically applied.
56129 然而,概率Chase算法的时间复杂度会随着测试码字个数的增加而增长; However, the time complexity of the stochastic Chase algorithm will increase as the number oftest test-vectors increases.
56130 在高阶调制下, SSCA算法产生测试码字时的搜索范围会随着调制阶数的增加呈指数增长,从而增大了硬件存储开销. In addition, under high-order modulation, the search range of generating test-vectorsin the symbol-level stochastic Chase algorithm (SSCA) will increase exponentially by the order of modulation,thus increasing the hardware storage consumption.
56131 为降低时间复杂度,本文提出了提前输出算法,不需要产生所有的测试码字即可实现成功译码. In order to reduce the time complexity, this paper proposes anearly output algorithm, which does not require all test-vectors to achieve successful decoding.
56132 仿真结果表明该算法可以在逼近原算法误帧率性能的同时将时间复杂度最多降低为原来的近1/τ(τ为测试码字个数). Simulation resultsshow that the proposed algorithm can approach the original stochastic decoding performance while reducingthe time complexity to nearly 1/τ (τ is the number of test-vectors).
56133 针对SSCA算法存储的压力,本文通过确定搜索半径辅助的选择方法来减小搜索范围. In view of the storage issue in the SSCA,this paper reduces the search range by search-radius-determination assisted selection method.
56134 仿真结果表明,提出的3σ-SSCA算法仅以少量性能损失为代价可将测试码字单个符号的搜索范围由q (q为调制阶数)个缩小为个位数. Simulation resultsindicate that the proposed 3σ-SSCA can reduce the search range of a single symbol of a test-vector from q (q isthe order of modulation) to less than ten at the cost of a small performance loss.
56135 区块链上的身份体制是不健全的. The identity system on Blockchain is defective.
56136 如何在区块链上认证某个用户的身份、如何确保身份的背书机构是真实的一直是一个挑战. There is a challenge of how to verify users’ identitiesand ensure the endorsements’ realities on Blockchain.
56137 运行在区块链上的分布式公钥基础设施可以在某种程度上解决上述问题,但是属性密码结合区块链可以提供更贴近于真实社会的身份模型. The decentralized public key infrastructure running onBlockchain can solve the above problems to some extent, but we can provide an identity-model closer to the realsociety with the combination of the attribute-based algorithm and Blockchain.
