Title:
A MULTI-CARRIER SEPARATION METHOD AND A MULTI-CARRIER SEPARATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/088809
Kind Code:
A1
Abstract:
A multi-carrier separation method and apparatus are provided by the present invention. Said method achieves digital frequency mixing by utilizing a frequency domain cyclic shift, and utilizes a Fast Fourier Transform (FFT)-based cyclic convolution to equivalently achieve a linear block convolution, which is then multiplied by the low frequency window in the frequency domain to achieve low pass filtering. At the same time, the method also utilizes other various means for reducing the amount of unit sample point calculations, which greatly reduces the amount of multi-carrier separation calculations, saves hardware resources, and reduces cost.
