摘要:
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.
摘要:
A method is provided for transmitting a multicarrier spectrum-spread signal, using a plurality of spreading codes. The method includes a step of allocating a power and/or rate to each of the spreading codes, based on an information representing the noise and/or on an information representing the quality of the link, said allocating step taking into account a target rate.
