Description: 介绍了一种基于锁频锁相环(FPLL)的载波跟踪算法。频率跟踪模块可以适应较大动态范围的频率变化，基于软件的数控振荡器(NCO)模块可以达到极高的频率跟踪精度。由于有锁频环的频率牵引，锁相环路滤波器可以设计得很窄，具有很好的抑噪性能，满足精确跟踪载波相位的要求。因此，该基于FPLL的载波跟踪算法可以适应信号存在较大的动态范围和噪声干扰的应用环境；同时，其鉴频鉴相算法表达式简单，易于用可编程数字器件实现。-Introduce an approach based on frequency-locking phase-locked loop (FPLL) carrier tracking algorithm. Frequency tracking module can adapt to a larger dynamic range of the frequency change, software-based numerical control oscillator (NCO) module can achieve the very high frequency tracking accuracy. Because of the frequency lock loop traction PLL filter can be designed very narrow, with very good noise suppression performance, to meet the precise requirements of carrier phase tracking. Therefore, the FPLL carrier-based tracking algorithm can be adapted to signal the existence of a larger dynamic range and noise of the application environment at the same time, the PFD algorithm expression is simple, easy to use programmable digital devices.

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.
