系统设计方案 OFDM(正交频分复用)技术实际上是MCM(Multi-Carrier Modulation
OFDM(正交频分复用)技术实际上是MCM(Multi-Carrier Modulation,多载波调制)的一种。其主要思想是,将信道分成若干正交子信道,将高速数据信号转换成并行的低速子数据流,调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开,这样可以减少子信道之间的相互干扰(ICI)。每个子信道上的信号带宽小于信 ...

数值算法/人工智能 a sub-cell WENO reconstruction method
We introduce a sub-cell WENO reconstruction method to evaluate spatial derivatives in the high-order ADER scheme. The basic idea in our reconstruction is to use only r stencils to reconstruct the point-wise values of solutions and spatial derivatives for the 2r-1 th order
ADER scheme in one dimensio ...
书籍 MULTI-CARRIER DIGITAL COMMUNICATIONS
Multi-carrier modulation‚ Orthogonal Frequency Division Multi-
plexing (OFDM) particularly‚ has been successfully applied to
a wide variety of digital communications applications over the past
several years. Although OFDM has been chosen as the physical layer
standard for a diversity of important ...

Since the principle of multi-carrier code division multiple access (MC-CDMA) was
simultaneously proposed by Khaled Fazel et al. and Nathan Yee et al. at the IEEE
International Symposium on Personal, Indoor and Mobile Radio Communications
(PIMRC) in the year 1993, multi-carrier spread spectrum (MC-SS ...
学术论文 基于FPGA技术的微弱GPS信号实时处理的实现.rar
普通GPS接收机在特殊环境下,如在高楼林立的城市中心,林木遮挡的森林公路,特别是在隧道和室内环境的情况下,由于卫星信号非常微弱,载噪比(Carrier Noise Ratio,C/No)通常都在34dB-Hz以下,很难有效捕获到卫星信号,导致无法正常定位。恶劣条件下的定位有广阔的发展和应用前景,特别是在交通事故、火灾和地震等极端环 ...
