宽带信道 - In the field of aeronautics and astronautics , people use different communication systems , which causes different types of signals to be separated in different sub - frequent bands ( sub carriers ) of a broad channel . in each sub - frequent band , signals can be modulated by different modulation methods and people can also use different multiple access methods . so a kind of communication system is required , which can receive all the sub - frequent band signals rapidly and correctly
在航空航天领域的通信中，人们使用不同的体制进行通信，这往往引起不同类型的信号分布在一个宽带信道的不同子频段(子载波)上，每个子频段中的信号可能使用不同的调制方式，也可能使用不同的多址方式，所以，人们需要一种能够快速与准确地接收各个子频段上的信号的通信系统。 - Cdma ( code division multiple access ) technology is used in communication system abroad because of its merit , people use cdma technology to transmit data , image and also other different information in different sub - frequent bands of a broad channel . so a research , which combines multi - carrier signal processing and cdma technology and processes different sub - frequent bands signal at same time , is full of practicable value
Cdma技术由于其优点被广泛采用在通信系统中，人们在一个宽带信道的不同子频段上使用cdma技术传输数据、图像等不同信息，所以将多载波信号处理与cdma技术联系起来进行研究，并且同时将不同的子频带信号进行处理是一个很有实用价值的问题。 - The main achievements of the dissertation are included : ( 1 ) the limitations of the traditional channelized reconnaissance receivers indicate that it cannot be used to receive the ultra - wide radar signal . it is pointed that the ultra - wide receiver must satisfy ultra wide monitoring band , high sensibility , wide dynamic range and almost real - time response
论文主要工作如下: ( 1 )分析了多种传统信道化接收机的结构性能,及其在超宽带信号接收中的局限性,指出超宽带信道化接收机必须满足实时性、高灵敏度和大动态范围等性能。 - The capacity of subliminal channels in elgamal signatures is studied . the capacity of broadband channel and the optimal schemes in 18 general elgamal signatures are analyzed . the relation between the capacity and the embedding rate of narrowband subliminal channels based on the exhausting search is studied
给出了容量的定义，理论上界以及影响容量的几个因素，给出了嵌入成功率和信道使用率对容量的影响，研究了elgamal签名中宽带信道的容量，分析了18种广义elgamal签名中的宽带阈下信道的容量并指出了最优方案，具体研究了基于搜索的窄带信道的容量与嵌入成功率的关系，具体研究了牛顿信道的带宽。
