摘要： A communication terminal (24A) includes first and second transmitters (28, 32A, 32B), which are coupled to produce respective first and second Radio Frequency (RF) signals that are phase-shifted with respect to one another by a beamforming phase offset, and to transmit the RF signals toward a remote communication terminal (24B). The terminal includes a reception subsystem (32A, 32B, 52) including first and second receivers (32A, 32B) and a phase correction unit (52). The first and second receivers are respectively coupled to receive third and fourth RF signals from the remote communication terminal. The phase correction unit is coupled to produce, responsively to the third and fourth RF signals, a phase correction for correcting an error component in the beamforming phase offset.

摘要： A communication system (20) includes first and second transmitters (36A, 36B), 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 receiver (32) includes an input circuit, which is coupled to at least one antenna (28) so as to receive, process and digitize first and second signals, thus generating first and second streams of input samples. An interference cancellation circuit (46) in the receiver includes first and second adaptive filters (64, 66), which are respectively coupled to filter the first and second streams of input samples using respective first and second coefficients to generate respective first and second filter outputs. A phase rotator (68, 71) is adapted to apply a variable phase shift compensating for a phase deviation between the first and second signals, the phase rotator having at least one configuration parameter. A control module (67) is operative to estimate signal characteristics of the interference cancellation circuit and to set the at least one configuration parameter of the phase rotator responsively to the estimated signal characteristics.

摘要： A method for communication includes receiving over a communication link (20) data that has been encoded using a forward error correcting (FEC) code. The encoded data is decoded using an iterative decoding process, which produces metrics. A condition of the communication link is assessed responsively to the metrics.

摘要： A method for antenna alignment includes defining a first link budget for wireless communication between first and second communication systems (24, 28) via respective first and second antennas (48, 52) in a normal operational mode in which a main lobe of the first antenna points toward the second antenna. The first antenna is aligned to point to the second antenna responsively to an alignment indication provided by communicating between the first and second communication systems in an alignment operational mode having a second link budget greater than the first link budget.
