摘要： A communication apparatus includes transmission circuitry and a frequency conversion unit. The transmission circuitry is configured to down-convert an input Intermediate Frequency (IF) signal using a transmit (TX) Local Oscillator (LO) signal so as to produce a TX baseband signal, to up-convert the TX baseband signal to produce an output Radio Frequency (RF) signal, and to send the output RF signal to an antenna. The frequency correction unit is configured to estimate a frequency of the TX baseband signal or of the input IF signal, and to adjust the TX LO signal based on the estimated frequency so as to cause the transmission circuitry to down-convert the input IF signal to a predefined target frequency.

摘要： A method for communication includes receiving a signal, which carries data bits and is distorted by multiple impairments including one or more frequency offsets and one or more In-phase/Quadrature (I/Q) imbalances. A corrected signal is produced by applying to the received signal a sequence of corrections to compensate for the impairments. The sequence includes a first and a third correction of one correction type and a second correction of another correction type intervening between the first and third corrections in the sequence, the correction types consisting of frequency offset corrections and I/Q imbalance corrections. The data bits are extracted from the corrected signal.

摘要： A transmitter includes an Outdoor Unit (ODU) including circuitry, and an Indoor Unit (IDU) that is configured to predistort a signal based on a non-linearity model of the circuitry having one or more model parameters, and to forward the predistorted signal to the ODU. The ODU is configured to accept the predistorted signal from the IDU, to amplify and transmit the predistorted signal using the circuitry, to estimate the non linearity model parameters, and to send the estimated model parameters to the IDU so as to cause the IDU to apply the model parameters in predistoring the signal.

摘要： A communication system includes first and second transmitters, which are coupled to transmit respective first and second Radio Frequency (RF) signals carrying first and second data over a wireless communication channel. The transmitters are coupled to select an operational mode from a group of operational modes and to operate in the selected operational mode. The group of the operational modes includes at least two of a protection mode, wherein the second transmitter serves as backup to the first transmitter, a spatial multiplexing mode, in which the first data is different from the second data and the first and second transmitters transmit simultaneously, and a beam-forming mode, in which the first data is identical to the second data, the second RF signal includes a phase-shifted replica of the first RF signal, and the first and second transmitters transmit simultaneously.

摘要： A method for communication includes transmitting data from a transmitter to a receiver using Adaptive Coding and Modulation (ACM). The data rate is set by selecting, based on feedback, an ACM profile defining a Forward Error Correction code and a modulation scheme. Upon detecting that the feedback is unusable, an operation of the transmitter is changed independently of the feedback.In another method, data is exchanged over two opposite directions of a bidirectional link that uses ACM by communicating using two ACM profiles. A joint constraint is defined on the two directions. The two ACM profiles are set based on first and second measured reception quality metrics of the two link directions, to meet the joint constraint. In yet another method, a subset of the ACM profiles is temporarily disabled, and the data is transmitted using only the ACM profiles that are not disabled.

摘要： A method for communication includes sending first data over a first communication link to a destination communication system at a first data rate, which can be varied. Second data, including at least a portion of the first data, is sent over a second communication link from the source communication system to the destination communication system at a second data rate, which can be varied. First and second data rates of the respective first and second communication links are dynamically set. At least the portion of the first data is selectively extracted from one of the first and second data at the destination communication system. In some embodiments, the first data equals the second data, and the data is extracted without data loss.
