In the first chapter , the basis of communication and channel coding theory is introduced briefly , the present situation of the development of error - correcting code and ldpc codes are pointed out . the second chapter introduces the tdd beyond 3g system model , including the system ’ s demand , the system ’ s target and the system ’ s basic parameter 第一章介紹了通信系統(tǒng)、信道編碼理論的基礎(chǔ)知識(shí)、糾錯(cuò)碼的發(fā)展?fàn)顩r, ldpc碼的提出及其發(fā)展,第二章介紹了我校設(shè)計(jì)的tddbeyond3g系統(tǒng)模型,包括系統(tǒng)的設(shè)計(jì)要求、指標(biāo)及系統(tǒng)的基本參數(shù)。
For its close relation to cryptography , coding theory and sequences , almost difference sets have attracted many scholars " attention . firstly , davis called a special kind of divisible difference set ( dds ) almost difference set . another kind of almost difference sets was defined by ding etc . for constructing binary sequence with three - level autocorrelation 最早, davis稱一類特殊的可分差集( dds )為幾乎差集,而后, ding等人為構(gòu)造具有優(yōu)的3級(jí)自相關(guān)函數(shù)的二元序列給出了幾乎差集的另一定義,并且利用分圓數(shù)構(gòu)造了很多類的幾乎差集。
In this paper , firstly , we introduce the relevant background and the coding theory . subsequently , we present the error - correcting scheme in this ssr system and elaborate on rs encoding / decoding algorithms and then simulate the selected codes " error - correcting capability . finally , we implement rs codec with fpga technology and the experiments show that desired targets can be achieved 本文首先介紹相關(guān)背景和編碼理論,接著提出糾錯(cuò)碼的設(shè)計(jì)方案,介紹rs編譯碼算法,并對(duì)其性能進(jìn)行仿真,最后設(shè)計(jì)出rs編譯碼器的硬件電路,后期的試驗(yàn)表明編譯碼器達(dá)到了預(yù)期的糾錯(cuò)性能。
Coding theory is the study of the properties of codes and their fitness for a specific application. Codes are used for data compression, cryptography, error-correction and more recently also for network coding.
