摘要： With advanced compute capabilities and growing convergence of wireless standards, there is requirement to run multiple wireless standards, e.g., 4G, 5G, and Wi-Fi, on a single hardware together. Typical solution includes reserving some computing resources for specific wireless standards. Such a resource strategy may not be optimized or efficient according to the real needs for various wireless standards. The present disclosure presents embodiments of using a unified resource controller to take multiple scheduling inputs across various wireless standards, allocate resources among a plurality of configurable processing units, and manage hardware components for data path accelerations including forward error correction, and signal processing implementation. The multiplexing multiple wireless technologies based on spectral utilization may improve the efficiency in power consumption and hardware resources utilization.

摘要： A signal processing apparatus and method provides the ability to dynamically select a subset of subcarriers from a received frequency division multiplex (FDM), select which subsets of subcarriers are coherently combined per satellite, and translate the selected subcarriers into a FDM having a smaller bandwidth. There are at least two first phase aligners, a digital cross-connect, and at least two second phase aligners. The first and second phase aligners are configured to receive a pair of in-phase and quadrature pairs and provide automatic gain control and coherent combing of the pairs. The digital cross-connect is configured to receive the in-phase and quadrature pairs from the two phase aligners and associate any in-phase and quadrature pair with another. Preferably, the apparatus further includes dual front-end digital channelizers configured to convert signals into an in-phase and quadrature pairs which are input to the first phase aligners.

摘要： A low complexity howling suppression system and method for portable karaoke system are provided. In the howling suppression, at least one infinite impulse response (IIR) filters are introduced for estimating the acoustic feedback picked up by the microphone from the real environment, and thereby to cancel out the acoustic feedback from the microphone input signal.

摘要： A method, computer program product, and computing system for receiving a speech signal from each microphone of a plurality of microphones, thus defining a plurality of signals. One or more noise signals associated with microphone self-noise may be received. One or more self-noise-based augmentations may be performed on the plurality of signals based upon, at least in part, the one or more noise signals associated with microphone self-noise, thus defining one or more self-noise-based augmented signals.

摘要： One embodiment provides a method of sound source enumeration and direction of arrival (DoA) estimation. The method, the method includes estimating, by an enumeration module, a number of sound sources associated with an acoustic signal. The estimating includes selecting a specific parametric model from a generalized model. The generalized model is related to a microphone array architecture used to capture the acoustic signal. The method further includes estimating, by a DoA module, a direction of arrival of each sound source of the number of sound sources based, at least in part, on the selected model. The estimating the number of sound sources and estimating the DoA of each sound source are performed using a Bayesian framework.

摘要： According to a first embodiment, a method may include receiving, by a user equipment, a configuration for determining one or more antenna panel-wise cross-link interference measurements from a network entity configured to receive one or more downlink spatial directions. The method may further include calculating, by the user equipment, one or more interference estimates of UL interfering signals and related cross-link interference powers from the network entity. The method may further include transmitting, by the user equipment, one or more interference measurements based upon the configured flexible UL-to-DL cross-link specific resource configuration to the network entity.

摘要： For near field communications, inductive coils coupled to each communicating circuit are brought close together so that there is inductive coupling between the two coils. Data signals can then be relayed between the two circuits without any direct connection between them. However, the system is susceptible to common mode noise, such as ambient EMI. In addition to the "active" coil pairs used for transmitting and receiving data, a pair of "passive" coils is provided, proximate to the active coil pairs, that is only used for detecting the ambient EMI. The EMI signals detected by the passive coils are processed by a noise detector/processor, and the noise detector processor then controls the transmitters and/or receivers to at least partially compensate for the detected EMI signals. Transmit power or receiver thresholds may be controlled by the noise detector/processor to improve the signal-to-noise ratio, or other compensation techniques can be used.
