Methods of transmitting and receiving a multicarrier signal, and corresponding transmitter, receiver, return signal, and computer programs
Abstract:
The invention relates to a method of receiving a signal corresponding to a multicarrier signal transmitted via at least one transmission channel, the method comprising an estimation step (11) of estimating said channel and delivering overall information about said channel in the frequency domain, referred to as a “frequency response” and comprising frequency samples. According to the invention, such a method also comprises: a sharing step (12) of sharing said frequency samples in at least two frequency sample vectors; a transform step (13) of transforming said frequency sample vectors from the frequency domain to a transform domain and delivering, for at least one frequency sample vector, a partial response of said channel in said transform domain; and a feedback step (14) of transmitting a return signal back to said transmitter, the return signal conveying samples extracted from said partial responses and representative of said channel in said transform domain.
Abstract(Chinese):

本发明涉及一种接收与经由至少一个传输信道发射的多载波信号相对应的信号的方法，该方法包括：估计步骤（11），估计所述信道并传送关于频域中的所述信道的总体信息， 作为“频率响应”并且包括频率样本。 根据本发明，这种方法还包括：在至少两个频率样本向量中共享所述频率样本的共享步骤（12） 将所述频率采样矢量从频域变换到变换域的变换步骤（13），并且针对所述变换域中的所述信道的至少一个频率采样矢量递送部分响应; 以及将所述返回信号发送回所述发射机的反馈步骤（14），所述返回信号传送从所述部分响应中提取的样本并且代表所述变换域中的所述信道。
