摘要： A communication terminal includes first and second antennas for respectively communicating with first and second remote terminals and a single up-converter that is arranged to up-convert an input signal to produce an RF transmit signal. The communication terminal further includes a switching circuit, which is arranged to couple the single up-converter to the first antenna in order to transmit the RF transmit signal to the first remote terminal during first time intervals, and to couple the single up-converter to the second antenna in order to transmit the RF transmit signal to the second remote terminal during second time intervals, which do not overlap the first time intervals.

摘要： A method for communication using a modulation scheme defined in a signal space includes determining demodulation confidence levels at a plurality of points distributed over the signal space. Weights are assigned to the respective points responsively to the demodulation confidence levels. A signal is received and demodulated using an adaptive loop so as to derive a corresponding signal point in the signal space. The adaptive loop is adjusted responsively to a weight assigned to the derived signal point.

摘要： A method for communication includes receiving a composite signal (104), which carries data at a first data rate and includes multiple sub-signals (88, 96) that are interleaved in a time domain and are separated by boundary indicators. The received composite signal is demultiplexed into the sub-signals by automatically detecting the boundary indicators between the sub-signals in the composite signal. The sub-signals are demodulated using multiple respective demodulators (80) operating at second data rates that are lower than the first data rate so as to generate respective output data streams. The output data streams are combined so as to reconstruct the data at the first data rate.

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 receiver includes an input circuit, which is coupled to at least one antenna 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) includes first and second processing chains (50, 52, 54), which are respectively coupled to filter the first and second streams of input samples using respective first and second adaptive coefficients to generate respective first and second filter outputs, at least one of the first and second processing chains being further adapted to apply a variable phase shift so as to compensate for a phase deviation between the first and second signals. An adder (55) sums the first and second filter outputs so as to generate a third stream of output samples, which is representative of the first signal. A coefficient controller (58) is operative to set the first and second adaptive coefficients and to separately set the variable phase shift responsively to the output samples.
