ABSTRACT:
A received signal has been converted from a source symbol rate to another symbol rate by symbol repetition, then interleaved to form frames in which the same symbol sequence is repeated multiple times. The source symbol rate is identified by dividing each frame into various numbers of blocks, and determining whether each such division makes at least a certain proportion of the blocks identical. The source symbols are reproduced by identifying a subset of similar blocks from statistical properties of the blocks, and combining the signal values in the subset of blocks.
