摘要： Improved spur reduction architectures that improve linearity in direct radio frequency (RF) receiver architectures. Non-uniform sampling in the form of sampling clock phase (or frequency) modulation is used to induce phase (or frequency) modulation on signals that are being received from a given Nyquist zone. At the output of the ADC (analog-to-digital converter), the signals are de-modulated to remove the induced modulation based on the Nyquist zone that is being received. The de-modulation process results in non-desired spurious artifacts (interfering leakage signals and ADC spurs) being spread in the frequency domain. Strong spurious artifacts may be removed after measuring the induced modulation and de-modulating. For the case of weak spurious artifacts, the de-modulation for the desired Nyquist zone spread these signals in the frequency domain. Induced modulation on signals may also provide a dithering effect on the ADC.
摘要翻译：改进的直接射频（RF）接收机架构改善线性度的减少架构。以采样时钟相位（或频率）调制形式的非均匀采样用于对从给定奈奎斯特区域接收的信号进行相位（或频率）调制。在ADC（模拟 - 数字转换器）的输出端，信号被去调制，以消除基于接收到的奈奎斯特区域的感应调制。去调制过程导致在频域中扩展的非期望的伪伪影（干扰泄漏信号和ADC刺激）。在测量诱导的调制和解调后，可能会去除强杂散伪像。对于弱伪伪影的情况，期望的奈奎斯特地带的去调制在频域中扩展了这些信号。对信号的诱导调制也可能对ADC产生抖动效应。

摘要： Systems and methods are disclosed that provide ultra-wideband frequency hopping spread spectrum (UWB-FHSS) solutions for transmit and receive architectures. These UWB-FHSS transmit and receive architectures can transmit signals over an extremely wide bandwidth while using a relatively slow analog-to-digital converter (ADC) without suffering from unacceptable performance degradation. For example, ADCs can be used having sample rates lower than standard Nyquist criteria would require for the bandwidth of the spread spectrum utilized.

摘要： The present invention is a method and computer program for equalizing group delay and magnitude of a system for which a system response is known. The method and computer program are implemented via a finite impulse response (“FIR”) filter for the system, and the method broadly comprises the steps of: evaluating a desired response for the system as a function of an amplitude of the system and a phase of the system; separating the phase of the system into a linear component and a non-linear component; performing a first optimization by minimizing a weighted error between a desired response for the system and a cascaded response for the system as a function of an equalizing filter and a phase slope so as to obtain at least one local smallest error E(Ω) as a function of phase slope; and once the local smallest error E(Ω) is known, performing a second optimization to locate any existing global smallest error, wherein the global smallest error is within a set distance from the local smallest error.
