摘要： In a method for processing a signal received by a receiver, at a first wireless receiver (20, 62) a first signal (x(t), x1(t)) comprising first and second signal components is received. The first signal component is intended for the first wireless receiver (20, 62) and the second signal component is related to at least one of a sending signal (s(t)) generated by a transmitter (29, 69) or to a second signal (x2(t)) intended for a second wireless receiver (61). To the first wireless receiver (20, 62) a reference signal (r(t), r1(t), r2(t)) which is proportional to the sending signal (s(t)) or to the second signal (x2(t)). At the first wireless receiver (20, 62) and from the reference signal (r(t), r1(t), r2(t)) an estimation signal which estimates the second signal component is generated. A filtered signal (y(t), y1(t)) is generated by subtracting the estimation signal from the first signal (x(t), x1(t)).

摘要： In a first aspect, the invention provides to a device comprising a substrate and an electrical conductor arranged between two terminals (A, B) and shaped for forming an inductor comprising at least two loops (1, 2) and arranged such that, at least locally, the far field is reduced. This arrangement results in an inductor which radiates a smaller magnetic field, also referred to as reduced EMI, which results in less noise generated in other inductive parts of an electronic circuit or system. The invention further provides in an advantageous embodiment proper balancing of the parasitic resistance and capacitance. By doing so the physical mid-point of 8-shaped inductors becomes the electrical mid-point (MP) which is beneficial when the inductor is used in a circuit. In a second aspect the invention provides an electronic system comprising the device according to the invention, wherein the electronic system comprises an LC-based voltage-controlled oscillator comprising the inductor, the electronic system being one of a group comprising: a multi-channel TV-receiver, a full-duplex transceiver, and a co-banding system. All these systems benefit from the symmetrical properties of the inductor. The better far-field compensation leads to a smaller VCO pulling effect which leads to a better performance of the system.

摘要： A system and method provide adaptive filtering of radio frequency (RF) signals. Multiple signals are received in a predetermined RF spectrum, the signals including a desired signal and multiple potentially interfering signals. A first signal of the potentially interfering signals is down-converted to a baseband signal, and a power of the baseband signal is determined. When the power exceeds a predetermined threshold power, a first notch filter, corresponding to a frequency of the first signal, is activated.

摘要： An analog-to-digital converter (ADC1) of the Sigma Delta type provides a stream of digital output samples (OUT) in response to an analog input signal (IN). The analog-to-digital converter (ADC1) comprises a quantizer (QNT) that has a dead zone. The quantizer (QNT) provides a digital output sample that has a neutral value when the quantizer (QNT) receives an input signal whose amplitude is within the dead zone. A feedback path (DAC) within the analog-to-digital converter (ADC1) provides a feedback action only in response to a digital output sample that has a value other than the neutral value.

摘要： The present invention relates to a receiver apparatus, analog-to-digital converter apparatus, and method of converting an analog input signal into a digital output signal, wherein an additional direct feedforward path is introduced to compensate for peaking of feedforward structures while preserving frequency selectivity of the feedforward topology. In particular, the direct feedforward path (72) is provided with a scaling by a direct feedforward coefficient (ao) greater than zero and less than one. As a result, overshoot or peaking of classical feedforward topologies can be suppressed while providing interferer immunity, anti-aliazing effects and loop stability.
