Abstract:
A method of decoding an incoming symbol stream comprising a first plurality of bits, the first plurality of bits originating from an original plurality of bits from which ones of said original plurality of bits were deleted, comprising the steps of:filling said first plurality of bits with a first set of replacement values to replace the deleted ones of said original plurality of bits to generate a first reconstructed approximation of said original plurality of bits;convolutional decoding said first reconstructed approximation of said original plurality of bits to produce a first decoded information bit stream;performing error detection on said first decoded information bit stream;indicating whether errors are present in said first decoded information bit stream;modifying the first set of replacement values with a second set of replacement values, different at least in part from said first set of replacement values to create a second reconstructed approximation of said original plurality of bits;convolutional decoding said second reconstructed approximation to produce a second decoded information bit stream;performing said error detection on said second decoded information bit stream; andindicating whether errors are present in said second decoded information bit stream.
