Preserving the content of a communication signal corrupted by interference during transmission

摘要

A communication signal including a plurality of bursts that individually include a plurality of data symbols is processed by both interleaving diversity and duplication diversity prior to transmission in order to preserve the content of the signal when the signal is corrupted by interference during transmission of the signal. A received communication signal having a plurality of bursts that individually include a plurality of data symbols which have been processed for transmission by interleaving diversity is processed to recover the content of the signal when the signal is corrupted by interference during transmission of the signal. Upon determining that the received communication signal may have been corrupted by interference during transmission, the received signal is processed by inserting erasure symbols into a deinterleaver prior to deinterleaving of the data symbols. The erasure symbols are necessary for recovering the content of the transmitted interleaved data symbols.
