SYSTEM AND METHOD FOR OFDM RECEPTION IN THE PRESENCE OF DOPPLER EFFECT BASED ON TIME DOMAIN WINDOWING

摘要

An OFDM receiver for processing a OFDM received signal to perform OFDM reception in presence of Doppler, comprising: - at least two parallel processing chains, comprising each: - a time domain windowing (41, 51) for processing a OFDM block, said processing consisting in the multiplication, element by element of said OFDM block, by a set of predetermined coefficient, - a DFT block (42, 52) (such as FFT) for demodulating said windowed OFDM symbol into the frequency domain equivalent, characterized in that the windowings of said at least two parallel processing chains have complementary profile so as to avoid any loss of information throughout the OFDM sample. The invention also provides a process to be used in a OFDM receiver.
