Description: 本程序中得到的收端OFDM信号的频谱波形，是与其发端信号的排步有关的。在发端的
％ 载波安排上，128个载波有前后各32个载波是null载波(如果这前后各32各载波是带外频段，
％ 那么理论上它们都应该是零！)，中间的64个载波是数据载波。这样的排步很明显就是一个
％ 两边低，中间高的频谱形式。所以，收端也应该是这个轮廓。
-this process the resumption end of the spectrum OFDM signal waveform, with the originator of the signal further on the row. The originator% carrier arrangements, 128 of the carrier after a 32 carrier is null carrier (if it was around the 32 is the carrier frequency band. % then theoretically they should be zero!) the middle 64 carrier data carrier. This arrangement is obviously further 1% lower on both sides, in the middle of the spectrum form high. Therefore, the admission should end this profile.

Description: 该模型实现了一个通用的OFDM TX和RX，这是不依赖于任何特定的行业标准。该模型的目标是开发和研究不断（不是“突发”）载波同步和定时跟踪方案。该技术纳入然后可以扩展和修改，以标准的具体通讯套件。该模型采用了“收购”技术，它利用了循环前缀相关属性，以赶在试图完成罚款跟踪算法一帧的边界粗略的估计。该模型实现了一个16点64循环前缀的OFDM载波波形。在OFDM符号有16个飞行员，3后卫音（0，带边幅），并使用45 QAM的剩余数据流4。
这包括最新型的衰落信道，误码率计算，并改善控制回路动态。-This model implements a generic OFDM TX and RX, which is not tied to any particular industry standard. The objective of this model is to develop and explore a continuous (not “bursty”) carrier and timing tracking synchronization scheme. The techniques incorporated can then be extended and modified to suite specific communications standards. The model uses an “acquisition” technique that exploits the correlation properties of the cyclic prefix to get a rough estimate of the frame boundary before attempting to accomplish the fine tracking algorithms. The model implements a 64 carrier OFDM waveform with a 16 point cyclic prefix. The OFDM symbol has 16 pilots, 3 guard tones (0 amplitude at band edge) and uses 4 QAM for the 45 remaining data streams.
This latest model includes a fading channel, BER computation, and improved control loop dynamics.

Description: ofdm仿真，用matlab仿真实现ofdm，为初学者提供一条道路(The proposed secret data embedding and extraction in
OFDM is shown in figure 1.In order to achieve higher data
rate, the serial data stream bits are converted in to parallel data
output bits. Then the modulation schemes can be BPSK,
QPSK or QAM, which in turn assigns the complex data
points. The orthogonality between subcarriers is maintained
by IFFT and FFT pairs which also transforms frequency
domain components to time domain and vice versa. 64 point
IFFT is used in this methodology.)
