Abstract:
A method of determining a decoded signal from an encoded signal, the method comprising:receiving the encoded signal; performing a first decoding so as to determine a first intermediate data element, wherein the first intermediate data element is stored in a memory, and wherein the first decoding is based on the encoded signal; performing a second decoding so as to determine a second intermediate data element, wherein determining the second intermediate data element is based on the encoded signal and an interleaved version of the first intermediate data element that is read from the memory, and wherein the second intermediate data element is stored in the memory; iteratively performing the first decoding and second decoding, wherein the first decoding exploits an interleaved version of the second intermediate data element, wherein the second intermediate data element is read from the memory and wherein the first intermediate data element is stored in the memory, wherein the second decoding exploits an interleaved version of the first intermediate data element that is read from the memory, and wherein the second intermediate data element is stored in the memory; and determining the decoded signal from either the first or the second intermediate data elements.
