摘要： Device, system, and method of flicker noise mitigation. For example, an apparatus includes a digital adaptive filter to mitigate flicker noise from a received Orthogonal Frequency-Division Multiplexing (OFDM) signal, wherein the digital adaptive filter includes: a prediction filter to estimate a value of the flicker noise based on linear combination of past low-pass filtered signal samples; a trainer sub-circuit to modify a coefficient of the prediction filter based on a difference between: a known incoming signal filtered by the prediction filter in a training stage, and a locally-generated reference copy of the known signal; a first path including a first pair of analysis-synthesis filters; and a second, parallel, path including a second pair of analysis-synthesis filters and further including the prediction filter.

摘要： One aspect of the invention provides a novel scheme to synchronize signal reception for a receiver device. In one embodiment, multi-symbol correlation of a first signal and a reference signal is performed. The reference signal corresponds to symbols denoting a synchronization or alignment marker. For every first signal sample, an indication of the degree of similarity between a plurality of the first signal symbols and reference signal symbols is generate as a second signal. This second signal is then nonlinearly processed, linearly processed, and then nonlinearly processed over time to determine if indications of high degrees of correlation occur at periodic intervals. If so, then these are considered synchronization markers and are used to synchronize signal reception of the receiver device.

摘要： A system and method of controlling the spectrum of an orthogonal frequency division multiplexing (OFDM) signal. The method comprises receiving an input frame of data samples to be modulated onto orthogonal multi-carrier signals, performing frequency domain filtering and spectrum masking on the input frame of data samples, and modulating the respective frequency modified data samples onto a plurality of carriers. Such a system may include an over sampling logic to over sample the input data to increase the frequency resolution of the output spectrum, a wave shaping filter to perform frequency domain filtering of the input data, a spectrum mask to further modify the spectrum of the output signal, and an inverse fast Fourier transform (IFFT) to generate the modulated orthogonal multi-carrier signal. Another embodiment entails controlling the spectrum of the output OFDM signal by performing time-domain filtering.

摘要： Embodiments of a variable inductor and a communication device are generally described herein. The variable inductor may comprise a signal wire and a control wire to receive a direct current (DC) control current. The variable inductor may further comprise a magnetic material integrated with the signal wire and the control wire. When a DC control current applied to the control wires takes a first current value, an inductance between an input node and an output node on the signal wire may take a first inductance value. When the DC control current takes a second current value, the inductance between the input node and the output node may take a second inductance value.
