Abstract:
1. An interleaver device for joint transmission of first and second transport channels via a transmission channel, the first transport channel comprising a sequence of first interleaver units, and the second transport channel comprising a sequence of second interleaver units, each interleaver unit comprising at least one symbol, the interleaver device comprising: a convolutional interleaver for altering the sequence of the first interleaver units in accordance with a first convolutional interleaver specification, defining first transmission resources for joint transmission, so as to acquire an interleaved first transport channel comprising an altered sequence of first interleaver units, and for altering the sequence of the second interleaver units in accordance with a second convolutional interleaver specification defining second transmission resources for joint transmission, so as to acquire an interleaved second transport channel comprising an altered sequence of second interleaver units, wherein the second convolutional interleaver specification are derived from the first convolutional interleaver specification, so that the second transmission resources are different from the first transmission resources; and a combiner for combining the interleaved first transport channel and the interleaved second transport channel in accordance with the first or the second convolutional interleaver specification, so as to acquire a transmission stream for the transmission channel.
