首先观察openair1/README.TXT 可以发现每个目录下至少都有一个def.h文件来声明结构体和函数,extern.h来声明外部变量以及vars.h文件来声明变量,知道MODULATION是存放调制解调操作的 进入openair1\PHY\MODULATION\ofdm_mod.c,找到OFDM调制代码,OFDM输入信号在经过信道编码,交织,调制后成为比特流,通过IFFT及那个频域输入映...
The dot11DSSSOFDMOptionEnabled MIB object specifies whether the current PHY type has enabled the use of the hybrid DSSS-OFDM modulation. When the 802.11 station enables this option, the PHY combines the direct-sequence spread spectrum (DSSS) preamble and header with the orthogonal frequency division...
OFDM Modulation with Corresponding Parameters For comparison, we review the existing OFDM modulation technique, using the full occupied band, however, without a cyclic prefix. Get for symIdx = 1:numSymbols inpData2 = randi([0 1], bitsPerSubCarrier*L, 1); modData = qammod(inpData2, 2^...
正交频分多址(Orthogonal frequency-division multiplexing,OFDM)有时又称为分离复频变调技术(discrete multitone modulation,DMT)正交频分多址技术可以视为多载波传输的一个特例,具备高速率资料传输的能力,加上能有效对抗频率选择性衰减通道,而逐 渐获得重视与采用。
Therefore, in every control module of OFDM modulation and demodulation, some logic is dedicated to signal alignment.因此,在OFDM调制解调中的每个控制模块中都有一些逻辑信号专用于信号对齐。 该实例中也通过Avalon Stream信号sink_ready(输入准备好信号)和source_ready(输出准备好信号)来支持背压。循环前缀插入...
OFDM Modulation Modulate the uncoded input and the precoded input to create the OFDM and SC-FDMA signals, respectively. Note that both signals are modulated using the same OFDM modulation parameters, so that only the precoding distinguishes SC-FDMA from OFDM. Get % Modulate with OFDM xOFDM =...
Y = ofdmmod(X,nfft,cplen) modulates the frequency-domain input data subcarriers in X using the orthogonal frequency division multiplexing (OFDM) method with an FFT size specified by nfft and cyclic prefix length specified by cplen. For information, see OFDM Modulation. exampleY...
