Title:
多重搬送波と符号分割多元接続との変調技術の組合せを使用した受信機における等化方法
Document Type and Number:
Japanese Patent JP4585732
Kind Code:
B2
Abstract:
The invention concerns a method for receiving a signal using a multiple carrier and code division multiple access modulation, comprising a demodulating step by application of a mathematical transform of the temporal domain to the frequency domain, a step which consists in equalizing the transformed signal and a step which consists in despreading the equalized signal. The invention is characterised in that said equalizing step takes into account, for each of the components of said transformed signal, perturbations affecting the carrier bearing said component and at least one other of said carriers and at least some of said spread codes.
