最大似然解碼 的英文怎麼說
中文拼音 [zuìdàsìránjiěmǎ]
最大似然解碼
英文
maximum likelihood decoding-
Chapter is the most important part in this paper, we used pulse position modulation ( ppm ) and maxim - likelihood demodulation to increase the power efficiency, improve the ber, also we used rs ( reed - solomon ) code to correct the bunched bit error because of the atmosphere scintillation. with the ppm modulation / ml demodulation method and rs code, the performance of the system improved to a new stage
第四章是對無線光接入的調制解調和編碼技術的分析,也是本文的重點,比較了ppm調制和ook調制的帶寬和功率利用率、硬判決解調和最大似然解調對系統性能的改善,以及採用rs糾錯碼對系統性能的改善。It is an important method of error control coding technology to solve the problem of transmission dependability. viterbi decoding algorithm is a kind of maximum likelihood decoding. because it can gain higher decoding speed and have the fixed decoding interval, viterbi decoding is applied so widely
差錯控制編碼技術是解決傳輸可靠性的一種重要手段,維特比( viterbi )譯碼演算法是一種最大似然譯碼,它可以得到較高的譯碼速度以及譯碼計算時間固定,因而在通信系統中得到廣泛應用。
