Description: 一个OFDM符号128个有效符号，插入128个虚拟子载波
符号率（即有效数据率）fsymbol，而发送速率（需要包括虚拟子载波）2fsymbol
输入的数据需要2倍的发送数据率，以便进行内插，实现位定时跟踪，即4倍fsymbol采样率的调制信号
OFDM symbol Nfft=128 points
一个OFDM符号数据点 Nfft*2 = 256 ， Guard Interval点 ＝Ng*2=64
- a OFDM symbol 128 effective symbols, insert 128 virtual sub-carrier
symbol rate (i.e. valid data rate), and fsymbol sending rate (need to include virtual sub-carrier) 2fsymbol
input data need 2 times the sending data rate for interpolation, realize a timing tracking, namely fsymbol sampling rates four times the modulation signal
OFDM symbol Nfft = 128 points
a OFDM symbol of data points Nfft* 2 = 256, Guard Interval point = Ng* 2 = 64

Description: Skew detection and correction is very important task before pre-processing of an image and it is a major problem in scanned documents, if it
not detected correctly it will lead wrong result in future during image analysis. During the scanning of the document, skew is being often introduced in the
document image. To measure the processed time and speed taken by skew detection algorithm, the Fast Fourier Transform (FFT) technique is applied
as it is fast approach for finding the angle of skewed document. This technique is used by firstly applying DCT compression and thresholding on image
to reduce timing computation and after that Fourier spectrum is obtained. Further this spectrum is divided into four quadrants and detected skewed angle
of each quadrant is measured. And finally Input image is rotated by using bilinear interpolation method. Platform: |
