Method and a device for dynamically selecting orthogonal functions of an orthogonal transmission system
Abstract:
An interleaving method (1) and a frequency interleaver (EF) of data symbols. The data symbols are for allocation to carriers of a set of NFFT carriers of a module for multiplexing and modulation by orthogonal functions in a multicarrier transmitter device (EM). The method includes selecting in time-varying manner from the set of carriers, carriers that are dedicated to transmitting data symbols and in dynamically interleaving a block of carriers constituted by the selected carriers and by null carriers.
Abstract(Chinese):

数据符号的交织方法（1）和频率交织器（EF）。 数据符号用于分配到用于在多载波发射机设备（EM）中通过正交功能复用和调制的模块的一组NFFT载波的载波。 该方法包括从载波集合中选择专用于发送数据符号的载波，以及动态交织由所选载波构成的载波块和空载波。
