Title:
デジタル多重搬送波信号、該信号の構成方法とその送信及び受信方法
Document Type and Number:
Japanese Patent JP3784834
Kind Code:
B2
Abstract:
The invention concerns a multicarrier signal designed to be transmitted to digital receivers, especially in a non-stationary transmission channel, corresponding to the frequency multiplexing of several elementary carriers each corresponding to a series of symbols, two consecutive symbols being separated by a symbol time τ0, a signal in which, firstly, the spacing ν0 between two neighboring carriers is equal to half of the reverse of the symbol time τ0 and, secondly, each carrier undergoes an operation of filtering for the shaping of its spectrum having a bandwidth strictly greater than twice said spacing between carriers ν0 and is spectrum is chosen so that each symbol element is highly concentrated in the temporal domain and in the frequency domain.The invention also concerns the methods for the transmission and reception of such a signal.
