Periodogram-powe
说明： 平均周期图法和平滑平均周期图法估计功率谱
从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力进行实验!!
用周期图法和welch法分别估计了一下信号的功率谱密度。采样频率200Hz，时间序列长度2048，FFT数据点数2048。其中welch法使用hanning窗，窗口长度600．(Average periodogram and periodogram smoothing method to estimate the average power spectrum from the classical power spectrum estimation periodogram principle starting from the theoretical analysis of the limitations of its existence, with the Welch algorithm, amending them. Rely on the powerful Matlab numerical analysis and signal processing capabilities to experiment!! With periodogram and welch method were estimated signal power spectral density about. Sampling frequency of 200Hz, the time sequence length 2048, FFT data points 2048. Welch method which uses hanning window, the window length of 600.)

A semi blind technique for estimating the carrier frequency offset in OFDM communication systems is presented in this
paper. The fractional and integer frequency offsets are esti-mated by employing a few null subcarriers in the rst OFDM
symbol in a frame. While the conventional null subcarrier based methods estimate the offset by a single global search, the
proposed method employs a two stage estimator, which greatly minimize the computational complexity.
