Channel equalization for ieee 802 . 16 single - carrier modulation systems 16單載波調(diào)制系統(tǒng)的信道均衡技術(shù)
Since the underwater channel is nonstationary and the fades is frequency - selective , it is hard to use the real - time channel equalization technology 傳統(tǒng)的串行通信為了保證數(shù)據(jù)的可靠傳輸,必須實(shí)時(shí)地進(jìn)行自適應(yīng)的信道均衡。
Based on the above investigation an improved cyclic prefix based channel equalization algorithm is proposed . simulation results show it ' s feasible 對(duì)利用循環(huán)前綴進(jìn)行信道估計(jì)的方法提出改進(jìn),提高了信道估計(jì)的性能,仿真結(jié)果證明這種改進(jìn)是有效的。
This technology combines the frequency orthogonality of ofdm to cdma code design for grouping the codes and allows a significant reduction for the calculations in channel equalization 運(yùn)用ofdm中的頻率正交的概念將cdma碼進(jìn)行分組,從而大大降低信道均衡的計(jì)算復(fù)雜度。
Blind equalization is a technique that do not need training data and can do the job of channel equalization with only the knowledge of statistics of received signal 盲均衡技術(shù)是一種不需要發(fā)射機(jī)發(fā)送訓(xùn)練序列,只需已知信號(hào)的一些基本統(tǒng)計(jì)特性就能對(duì)信道進(jìn)行均衡的一種特殊的均衡技術(shù)。
In the end , the principle of multi - channels equalization is studied . according to the performance of gain - and - phase errors in the receivers , a simple and efficient method is put forward 在本文的最后分析了多天線、多接收通道間幅相不一致性的均衡原理,根據(jù)接收機(jī)對(duì)信號(hào)幅相不一致性特性的分析,提出簡(jiǎn)易可行的頻域補(bǔ)償方法。
In chapter 2 the principle of modulation techniques and channel equalization are introduced . simulation results are presented to illuminate the characters of gmsk modulation signal . then the channel equalization problem is advanced 第二章介紹了信道編碼及信道均衡的基本原理,主要針對(duì)gmsk調(diào)制信號(hào)的特點(diǎn)和gmsk碼復(fù)信號(hào)調(diào)制進(jìn)行了仿真,引出了信道均衡的問(wèn)題。
Channel equalization theory is presented in detail , together with adaptive equalization and blind equalization techniques . then , one of the most important measures on the performance of equalizers is introduced in the thesis 論文詳細(xì)介紹了信道均衡原理,概要地?cái)⑹隽俗赃m應(yīng)均衡,并且著重闡述了盲均衡,介紹了兩種常用的線性濾波器結(jié)構(gòu),給出了評(píng)判均衡器工作性能的重要指標(biāo)。
At the same time , an example about lms algorithm in channel equalization is applied to illuminate how to combine matlab programming code in lab view . the result show that this method is efficient and easy and it ' s a good way to expand lab view functions 同時(shí)以實(shí)現(xiàn)信道均衡lms算法為例介紹了labview調(diào)用matlab程序代碼的途徑,實(shí)踐證明,該方法高效、易行,是擴(kuò)展labview功能的一條很好的途徑。
