摘要： Examples described herein include systems and methods which include wireless devices and systems with examples of full duplex compensation with a self-interference noise calculator. The self-interference noise calculator may be coupled to antennas of a wireless device and configured to generate adjusted signals that compensate self-interference. The self-interference noise calculator may include a network of processing elements configured to combine transmission signals into sets of intermediate results. Each set of intermediate results may be summed in the self-interference noise calculator to generate a corresponding adjusted signal. The adjusted signal is received by a corresponding wireless receiver to compensate for the self-interference noise generated by a wireless transmitter transmitting on the same frequency band as the wireless receiver is receiving.

摘要： A pulse signal compensation circuit of a pulse generator can include a pulse measurement circuit and a compensation generator circuit. The pulse measurement circuit can be configured to receive a plurality of pulse signals and to generate an average duty cycle or pulse overlap signal proportional to the duty cycle or pulse overlap of the plurality of pulses. The compensation generator circuit can be configured to receive the average duty cycle or pulse overlap signal and generate a duty cycle or pulse overlap compensation signal based on the average duty cycle or pulse overlap signal. The compensation signal can be utilized to adjust the duty cycle, amount of positive or negative pulse width overlap, and or the like of the plurality of pulse signals.

摘要： A radio frequency (RF) communication assembly includes an RF communication circuit and a compensator apparatus. The compensator apparatus receives an input including an I-component of a pre-compensated signal, a Q-component of the pre-compensated signal, and encoded operating conditions of the RF communication circuit. The RF communication circuit includes RF circuit components causing signal impairments. The compensator apparatus perform neural network computing on the input, and the RF communication assembly generates a compensated output signal that compensates for at least a portion of the signal impairments.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a transmitting device, an indication of an instantaneous gain associated with an amplitude distortion associated with frequency division multiplexed downlink communications to the UE from the transmitting device. The UE may receive the frequency division multiplexed downlink communications from the transmitting device over frequency resources allocated to the UE, wherein receiving the frequency division multiplexed downlink communications comprises applying a digital post distortion model to the frequency division multiplexed downlink communications according to the instantaneous gain.

摘要： A signal processor and method of signal processing for a radio receiver is described. An input signal is received together with a spectral repetition interval value of an interferer signal. An interference reference signal is generated from the received spectral repetition interval value and the received signal. The received signal is adapted using the generated interference reference signal.

摘要： Various embodiments herein provide techniques for minimum mean-square error interference rejection combining (MMSE-IRC) processing of a received signal, distributed between a baseband unit (BBU) and a remote radio unit (RRU). The RRU may perform a first phase of processing based on an extended channel that includes a channel of one or more user equipments (UEs) served by the RRU and interference samples that correspond to other cells or additive noise. The first phase may include scaling the interference samples by a scaling coefficient to obtain a modified extended channel, and performing maximum ratio combining (MRC) on the modified extended channel to obtain a processed signal. The RRU may send the processed signal to the BBU for the second phase of processing. The second phase of processing may include regularized zero forcing to remove interference. Other embodiments may be described and claimed.

摘要： Methods, systems, and devices for wireless communications are described. A transmitting (Tx) device transmits, to a receiving (Rx) device, a control message indicating a location of one or more noise spurs associated with wireless communications performed by the Tx device using a set of resources, where the location includes a frequency location of the one or more noise spurs in the frequency domain. The Tx device then generates a data message to be communicated using the set of resources associated with the one or more noise spurs based on transmitting the control message, and transmits the generated data message to the Rx device using the set of resources associated with the one or more noise spurs. By indicating the location of the noise spurs, the Rx device may be more able to more efficiently identify and address (e.g., filter out, ignore) the noise spurs within the data message.
