    Abstract: A system comprises a microwave backhaul outdoor unit having a first resonant circuit, phase error determination circuitry, and phase error compensation circuitry. The first resonant circuit is operable to generate a first signal characterized by a first amount of phase noise and a first amount of temperature stability. The phase error determination circuitry is operable to generate a phase error signal indicative of phase error between the first signal and a second signal, wherein the second signal is characterized by a second amount of phase noise that is greater than the first amount of phase noise, and the second signal is characterized by a second amount of temperature instability that is less than the first amount of temperature instability. The phase error compensation circuitry is operable to adjust the phase of a data signal based on the phase error signal, the adjustment resulting in a phase compensated signal.

    Abstract: Methods and systems are provided for loop-through for multi-chip communication systems. Receiver circuitry, that is operable to receive one or more input feeds, may comprise a plurality of chips, each of which may be configurable to generate a corresponding output comprising one or more feed elements (e.g., channels) extracted from the input feed(s). However, only a first chip may be operable to handle reception and/or initial processing of the one or more input feeds, with each one of the remaining chips processing a loop-through feed generated by the first chip, in order to generate the corresponding output of that chip. The first chip generates the loop-through feed based on the one or more input feeds, such as after the initial processing thereof in the first chip. Generating the loop-through feed may comprise applying channelization (e.g., separately for each remaining chip), switching based processing, and/or interfacing based processing.

    Abstract: An electronic device may be operable to sample a signal during an analog-to-digital conversion using an analog-to-digital converter in the electronic device, and the signal may comprise a wide bandwidth and a plurality of channels. The electronic device may adaptively change a sample rate of the sampling to move aliasing out of a region of one or more desired channels of the plurality of channels. The electronic device may change the sample rate using a variable oscillator in the electronic device. The change of the sample rate may comprise, for example, increasing or decreasing the sample rate by a particular percentage. In response to the change of the sample rate, the electronic device may perform, using a variable rate interpolator in the electronic device, variable rate interpolation. The variable rate interpolator may comprise, for example, a finite impulse response filter.
