    摘要: The present invention relates to a 6G communication system for achieving high data transmission rates and ultra-low latency beyond 4G and 5G communication systems. According to one embodiment of the present invention, provided are a method and device wherein, in order to improve the coverage of a transmission end and the reception performance of a reception end, an AI model is trained on the PA input/output relationship at the reception end, and the trained AI model is used to compensate for PA nonlinearity in received data. In addition, according to one embodiment of the present invention, provided are a method and device wherein training of the AI model on the reception end is only instructed when training of the AI model is necessary, and a reference signal suitable for the training of the AI model is instructed. Accordingly, it is possible to reduce the signaling overhead, computational overhead, or power consumption generated during the training of the AI model. In addition, the reference signal having the same or similar characteristics as the data compensating for PA nonlinearity is used in the training of the AI model, and thus overfitting of the AI model can be prevented. Therefore, the AI model having optimal PA nonlinearity compensation performance can be obtained.

    摘要: The present invention discloses a digital predistortion processing method and system. The method includes: extracting a predistortion parameter corresponding to an input signal from a predistortion coefficient parameter list to perform predistortion processing on the input signal to obtain a forward sending signal; performing power amplification processing on the forward sending signal to obtain an output signal; collecting the output signal to obtain a feedback signal; collecting the forward sending signal after delaying for a preset number of sampling points to obtain a reference signal; performing synchronous correlation calculation on the reference signal and the feedback signal to calibrate the feedback signal; training a predistortion coefficient according to the reference signal and the calibrated feedback signal; and forming a predistortion coefficient parameter list according to the predistortion coefficient and the amplitude of the input signal. In this embodiment, the transmission signal is delayed for a preset number of sampling points to greatly perfect the radio frequency index ACPR.

    摘要: A method for remote crosstalk cancellation, includes: transmitting, by a DSL receiving end over a first line to a DSL transmitting end, a noise statistic related value that reflects a noise component of signal received on the first line: receiving, by the DSL receiving end over the first line from the DSL transmitting end, a synthesized signal pre-coded on the DSL transmitting end using filtering parameters associated with the noise statistic related value; and in response to the reception of the synthesized signal, transmitting, by the DSL receiving end over the first line to the DSL transmitting end, an updated noise statistic related value. A corresponding device and a signal processing system for remote crosstalk cancellation are provided. The self-adapting adjustment of the values of filtering parameters has a favourable astringency and an effect for crosstalk cancellation, avoiding the need to know the channel transmission matrix in advance, while absolutely avoiding the conflict to the existing transmission standard.

    摘要: A communications device may include a transmit path, a receive path operable simultaneously with the transmit path and at a same frequency as the transmit path, and processing circuitry. The processing circuitry may be configured to generate a baseband signal for the transmit path, generate a feedforward signal based upon the baseband signal, and use the feedforward signal to reduce self-interference in the receive path from the transmit path.
