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 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 jointly designing a transmitter pulse-shaping filter (36) and a receiver pulse-shaping filter (68) having respective filter coefficients includes defining one or more performance-related variables based on at least some of the filter coefficients of the transmitter and receiver pulse-shaping filters. One or more constraints applicable to one or more of the filter coefficients and variables are set. A cost function defined over the variables is evaluated. Optimized filter coefficient values of the transmitter and receiver pulse-shaping filters are jointly calculated by applying an optimization process to the cost function while meeting the one or more constraints.
