Patent ID: 7532562

Claim:
A method for communication, comprising: receiving a composite signal, which carries data at a first data rate and comprises multiple sub-signals that are interleaved in a time domain and are separated by boundary indicators; demultiplexing the received composite signal into the sub-signals by automatically detecting the boundary indicators between the sub-signals in the composite signal; and demodulating the sub-signals using multiple respective demodulators operating at second data rates that are lower than the first data rate so as to generate respective output data streams, and combining the output data streams so as to reconstruct the data, wherein receiving the composite signal comprises digitally recovering a timing of the composite signal by estimating a timing offset of at least one sub-signal by a respective demodulator, and correcting a corresponding timing offset in the composite signal using digital interpolation responsively to the calculated timing offset of the at least one sub-signal.
