该文针对OFDM系统频偏估计中所产生的模糊度问题提出了一种基于符号间相位差分调制的频偏估计模糊度校正算法。
In this paper, a novel frequency ambiguity resolution algorithm in OFDM systems based on phase differential modulation between adjacent symbols is proposed to correct the frequency ambiguity.
每个校正位试验的作用是如果(具有任何符号的)大噪声事件已对在前位试验做出了错误的判定，则使得ADC减少DAC误差。
The effect of each correction bit trial is to allow the ADC to reduce the DAC error if a large noise event (of either sign) has caused a wrong decision to be made on a previous bit trial.
估计并补偿频偏是为了实现载波同步，估计符号率和校正定时误差是为了实现码元同步。
Estimating and compensating carrier frequency offset are to achieve carrier frequency synchronization. Estimating symbol rate and correcting timing error are used to synchronize symbol.
