Full Diversity LDPC Codes Design and Energy Efficiency Analysis for Clustering Wireless Sensor Networks

  • 摘要: 高效的差錯控制編碼技術(shù)(ECC)可以增強(qiáng)無線傳感器網(wǎng)絡(luò)傳輸穩(wěn)定性、網(wǎng)絡(luò)的能量利用效率。為了充分利用無線傳感器網(wǎng)絡(luò)中蘊(yùn)含的分集資源應(yīng)對惡劣信道環(huán)境導(dǎo)致的高差錯概率,該文研究了基于根校驗(yàn)全分集LDPC碼的差錯控制編碼技術(shù)。首先,提出在分簇?zé)o線傳感器網(wǎng)絡(luò)中,基于根校驗(yàn)全分集LDPC碼的編碼方案;其次,設(shè)計(jì)了適用于所提方案的速率兼容全分集LDPC碼字結(jié)構(gòu)。最后,分析了所提編碼系統(tǒng)的能效。仿真結(jié)果表明,在信道條件較差的環(huán)境中(仿真中,信道噪聲大于410-4 mW),采用該文的編碼方案,能夠顯著提高無線傳感器網(wǎng)絡(luò)的能效。
