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: 还在为“基于MATLAB的OFDM系统仿真”的朋友，可以看看我总结的资料！
该代码通过综合了本站中的两个源代码，在MATLAB 7.0下完成OFDM系统的完美仿真：音频数据采集->S/P转换->16QAM映射->IFFT处理->添加CP->P/S->理想/多径信道传送->……（FFT等）->传输结果比较（前后频谱图、可以直接通过听前后的音频文件来辨别系统的好坏-理想信道时音质前后相同）。在此还要感谢那两位站员提供相关的代码，也希望能对其他人有帮助。更希望本站能吸引更多的编程爱好者再创佳绩。-KEYWORD:OFDM MATLAB 7.0 CP IFFT FFT P/S S/P
Also for the " Based on MATLAB simulation of the OFDM system," a friend, you can see my summary of the information! The code through a combination of the two site source code, MATLAB 7.0 at complete perfection OFDM system simulation: Audio Data Acquisition-> S/P conversion-> 16QAM mapping-> IFFT processing-> Add CP-> P/S-> ideal/multi-path channel transmission-> ... ... (FFT, etc.)-> transmission results (before and after the frequency spectrum can be directly before and after listening to audio files to identify the system good or bad- when the ideal channel before and after the same sound quality). This would also like to thank at the two stations to provide the relevant code, also hope to have helped others. I also hope to attract more site programming enthusiasts new heights.

Description: 认知无线电能有效缓解无线电频谱资源匮乏问题，正交频分复用（OFDM）非常适合认知无线电系统。动态频谱资源分配是认知系统的一项重要功能。本文的目标就是最小化成本函数，这个函数考虑到主用户以及次用户的干扰功率。-Cognitive radio (CR) is a promising concept for improving the utilization of scarce radio spectrum resources. Orthogonal frequency division multiplexing (OFDM) is regarded as a technology which is well-matched for CR systems. Dynamic resource allocation is an important task in such systems. A novel resource allocation algorithm for multiuser OFDM cognitive radio system is presented in this paper. The objective is to minimize a cost function which takes into account the interference
power experienced by the primary user as well as the base station transmit power for secondary users given minimum bit rate requirements for each secondary user.

Description: 正交频分复用（OFDM，Orthogonal Frequency Division Multiplexing）是一种多载波数字调制技术，也可以被当作一种复用技术。具有频谱利用率高、抗多径干扰等特点，OFDM系统能够有效地抵抗无线信道带来的影响，例如信道的频率选择性衰落，脉冲噪声和共信道干扰的影响。本文主要介绍了OFDM原理的相关知识。-The Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) is more than one kind of carrier digital modulation technology, may also treat as one kind of multiplying technology. Has the frequency spectrum use factor high, characteristics and so on anti-multi-diameter disturbance, the OFDM system can resist the influence which effectively the wireless channel brings, for example channel s frequency selectivity declines, impulse noise/pulse noise/pulsive noise and altogether channel disturbance influence. This article mainly introduced the OFDM principle related knowledge.
