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: A signal processing circuit, which is within a satellite reception assembly, may be operable to analyze actual frequency information corresponding to a plurality of downconverted signals. Each of the downconverted signals may be downconverted using one or more corresponding local oscillators (LOs). Based on the analyzing, one or more of the following may be determined: one or more frequency offsets associated with the one or more corresponding LOs and one or more actual guard bands. The signal processing circuit may generate information on the determined frequency offsets and the determined actual guard bands. The signal processing circuit may perform, based on the generated information, one or both of a band stacking operation and a channel stacking operation so as to prevent channels/bands being stacked on each other or being overlapped. The signal processing circuit may perform, based on the generated information, frequency corrections for channel tuning in a gateway.
