摘要： An RF transceiver includes an RF transmitter coupled to a broadcast antenna, an RF receiver coupled to a receiving antenna, and a communication channel to provide an RF reference signal from the transmitter to the receiver to assist in canceling a transmitter-induced interference signal at the receiver. A digital processor of the receiver is configured for adaptive filtering the RF reference signal in the frequency domain to estimate the spectrum of the interference signal, and estimating a spectrum of a remotely-transmitted signal based on the estimated interference spectrum and a spectrum of a received signal from the receiving antenna. The filtering includes estimating frequency-domain filter weights based, at least, on spectra of the received and reference signals, and de-noising of the estimated filter weights. The interference cancellation may be iteratively improved using a re-modulated feedback from a demodulator and/or a decoder in the signal processing chain of the receiver.

摘要： A voltage controlled delay line (VCDL) for measuring the maximum speed of a chip includes a first input configured to receive a reference clock signal, a first output configured to output an output clock signal, and a second input configured to receive a phase error signal representing a phase delay between the reference and output clock signals. A register stores a delay code applied by the VCDL to the reference clock signal to delay the reference clock signal to generate the output clock signal. The delay code is adjusted according to the phase error signal until the phase delay is equal to a predetermined value. A second output is coupled to an interface that reads the delay code from the register and outputs the delay code to automated testing equipment when the phase delay is equal to the predetermined value. The outputted delay code corresponds to the maximum chip speed.

摘要： A coding method is adapted to select different codebook search algorithms according to varied types of input signals. An encoder using the coding method is also provided. As appropriate search algorithms may be selected according to all possible structural features of the input signals, certain types of signals for which satisfactory results may be obtained through simple computations may match with search algorithms suitable for these signal types and having low computation complexities, so as to achieve better performance with fewer system resources. Meanwhile, other types of signals that need complicated computations may be processed by more sophisticated search algorithms, thereby ensuring the coding quality.

摘要： Embodiments include devices and methods for adaptive image processing in an umnanned autonomous vehicle (UAV). In various embodiments, an image sensor may capture an image. Images may be obtained during motion or hover modes of the UAV. The UAV may determine whether stabilizing a line of the image causes a breach of an image crop margin. That is, the UAV may estimate or begin to adjust image distortion and crop the image, and may evaluate during or after the estimation/adjustment whether an image crop margin is breached by the result. The UAV may reduce stabilizing of the line of the image in response to determining that stabilizing the line of the image causes a breach of the image crop margin.
