The columns and rows are constrained by each other. the simulations over binary symmetric channe ( lbsc ) and gilbert - elliott channel ( gec ) shows the performance is great improved, especially over burst error channel peak signal to noise ratio ( psnr ) is improved more. it is tried to be used in wireless communication system
模擬結果表明,採用行列交替約束的約束維特比譯碼以後,性能得到較大的提升,尤其在突發錯誤通道中,傳輸的圖像經乘積編碼進行通道編碼與譯碼后峰值信噪比有明顯的提高。Shortwave channel is time varying transmission channel. it has dispersion in frequency and time domains. this characteristics hinds the data transmi - ssion at high speed and the correction of received data. in this dissertation i have analyzed the statistic characteristic of shortwa - ve channel, established the model of shortwave channel and simulated the rayl eigh fading distribution. the technology of spreading spetrum has been proved that it has the capability for anti - multipath and discerning multipath
在短波通信中,由於通道的時間色散和頻率色散,引起多徑展寬和多徑衰落,前者限制了數據的傳輸速率,後者造成短波數據通信中出現突發錯誤,為了解決多徑效應對短波通信的影響,本文所做工作如下:首先詳細分析了短波通道的統計特性,建立其數學模型;其次分析了擴頻通信的特點,從理論上證明擴頻技術不僅具有抗多徑干擾能力,而且具有分離多徑的能力;介紹了傳統的rake分集合併技術的特點。Reed - solomon code, a powerful error correcting code for burst and random errors, is widely applied to deep space communications, mobile communications, disk array, digital video broadcasting system, and so on
Reed - solomon (簡稱rs碼)是一種具有很強的糾正突發和隨機錯誤的通道編碼方式,在深空通信、移動通信、磁盤陣列以及數字視頻廣播( dvb )等系統中具有廣泛的應用。Reed - solomon code, a powerful error correcting code for burst and random errors, is widely applied to deep space communications, mobile communications, disk array, digital video broadcasting system ( dvb ), and so on
Reed - solomon碼(簡稱rs碼)是一種具有很強糾正突發和隨機錯誤能力的通道編碼方式,在深空通信、移動通信、磁盤陣列以及數字視頻廣播( dvb )等系統中具有廣泛的應用。When there are less random errors in the channel, inner code can be utilized to correct them ; when there are lasting accidental errors or too many random errors beyond the inner code ' s capacity,
當通道產生少量的隨機錯誤時,通過內碼就可以糾正。當產生較長的突發錯誤或隨機錯誤很多,超過內碼的糾錯能力,則內譯碼器產生錯譯,輸出的碼字有幾個錯誤。Many of communication systems take the convolutional code and viterbi algorithm as the channel coding scheme. the viterbi algorithm decoding is a kind of maximum likelihood decoding, and its performance is good over additive white gaussian noise ( awgn ) channel, but when burst errors occur, the decoding performance may be greatly degraded
維特比譯碼演算法是最大似然譯碼,在由高斯白噪聲引起的隨機錯誤的通道中有良好的性能,但當通道錯誤集中或為突發錯誤通道時,維特比譯碼演算法則性能急劇下降。This paper proposes a multiple description mesh - based motion coding method, which generates two descriptionsfor mesh - based motion by subsampling the nodes of a right - angledtriangular mesh and dividing them into two groups. motion vectorsassociated with the mesh nodes in each group are transmitted overdistinct channels
丟包由於網路阻塞路由延遲以及從高容量網路向低容量網路交換等和通道失效由於衰落效應和突發錯誤等使得在internet和無線通道上壓縮視頻數據的可靠傳輸成為新的研究課題。However, in actual channels, rs code need be applied in combination with interleaving and scrambling in most cases to deal with sudden errors that break out continuously
而在實際通道中,由於常常要對付連續出錯的突發錯誤,因此rs碼常常還要與交織和加擾結合應用。分享友人
