地上波受信機のためのデジタル復調器

Document Type and Number:

Japanese Patent JP4232870

Kind Code:

B2

Abstract:

A method and a demodulator for processing a Fast Fourier Transform using data blocks include a Fast Fourier Transform (FFT) coprocessor and a digital signal processor (DSP). The FFT coprocessor includes a start function and a computation function (F_FFT). The start function is adapted to generate a start signal each time a first data of a new block is received. The DSP includes a time error function which indicates to the start function for how much data it has to wait before a new start signal is generated.
