Based on the coherent reception theory of radio signals and the theory of digital signal processing , the effects of carrier frequency offset , sampling clock offset , and symbol timing offset on ofdm signals are exploited . a series of amendments and new algorithms is derived from the in being algorithms of guard interval based symbol timing and frequency offset estimation , frequency - domain frequency offset , sampling offset , and symbol timing offset estimation
以无线信号的相干接收和数字信号处理理论为基础，就载波频偏、采样钟偏差和符号定时偏差对ofdm信号的影响进行了分析，对基于保护间隔的符号定时与载波频偏估计算法和多种现有频偏、采样钟与符号定时偏差的频域估计算法进行了研究，提出了一系列改进措施与新算法。
