    Abstract: Disclosed are a predistortion method and system, a device, and a non-transitory computer-readable storage medium. The predistortion method is applicable to a predistortion system which may include a predistortion multiplier, a complex neural network, and a radio frequency power amplifier output feedback circuit. The method may include: inputting a training complex vector to the predistortion system to obtain a complex scalar corresponding to the training complex vector, which is output by the predistortion system; training the predistortion system based on the training complex vector and the complex scalar until a generalization error vector magnitude and a generalization adjacent channel leakage ratio corresponding to the predistortion system meet set requirements; and inputting a service complex vector to the trained predistortion system to obtain a predistortion corrected complex scalar.

    Abstract: A multi-user code division multiple access communication method, and corresponding transmitter and receiver include: the transmitter determines a complex-valued spreading sequence to be used by the transmitter, herein each element of the complex-valued spreading sequence is a complex number and values of real and imaginary parts of all elements in the complex-valued spreading sequence are from an M-element set of real numbers, and M is an integer larger than or equal to 2; the transmitter performs spreading processing on data symbols to be sent by using the complex-valued spreading sequence to generate a spread symbol sequence; and sends the spread symbol sequence. The receiver receives signals transmitted by multiple transmitters, and performs reception detection by using an interference cancellation signal detector, herein the complex-valued spreading sequences used by the multiple transmitters are used during detection.

    Abstract: Provided are message transmitting or receiving methods and devices, a base station, and a terminal. Uplink access signals are divided into a first pre-determined number of uplink access signal groups. An uplink access signal, which is transmitted in an uplink access beam form based on one or more uplink access signal groups, is received from a second communication node. An uplink access signal group to which the uplink access signal pertains is determined. One or more uplink access signals contained in the uplink access signal group are transmitted under at least one of the following restriction conditions: a restricted sequence transmitting order, a restricted transmitting occasion, and a restricted transmitting frequency domain position. An uplink access response message is transmitted to the second communication node over an uplink access response resource corresponding to the determined uplink access signal group.

    Abstract: The present invention discloses methods and apparatuses for quantizing, and feeding back channel information and precoding data. In the above methods, a channel measurement pilot signal is received from a base station. The channel information is acquired by performing channel measurement according to the channel measurement pilot signal. CMatrix1 and CMatrix2 are calculated using the channel information, herein CMatrix1 and CMatrix2 are used to quantize the channel information or indicate the base station to perform precoding. And first indication information of CMatrix1 and/or second indication information of CMatrix2 are fed back to the base station. According to the technical solutions of the present invention, as the influence of the polarization leakage is considered in the feedback design, a significant performance gain exists in a case that the polarization leakage actually occurs.
