Temporally separating and re-organizing data using two-stage interleaving and de-interleaving

摘要

The present invention is a method and apparatus for temporally separating an input data stream in a transmit circuit and for re-organizing a temporally separated input data stream in a receive circuit.In the transmit circuit, a first interleaver interleaves the serial input data stream. A first converter is coupled to the first interleaver to convert the interleaved serial input data stream into groups of N-bit words where N is a positive integer. A second interleaver is coupled to the first converter to interleave the groups of N-bit words. A second converter is coupled to the second interleaver to convert the interleaved groups of N-bit words into a serial output data stream. The output data stream corresponds to the temporally separated input data stream.In the receive circuit, a first converter converts the serial input data stream into groups of N-bit words where N is a positive integer. A first de-interleaver is coupled to the first converter to de-interleave the groups of N-bit words. A second converter is coupled to the first de-interleaver to convert the de-interleaved groups of N-bit words into interleaved serial data. A second de-interleaver is coupled to the second converter to de-interleave the interleaved serial data into an output data stream. The output data stream corresponds to the re-organized input data stream.
