A turbo decoder decodes encoded data using a regenerated interleaver sequence. An addressable column index memory stores column indexes of the encoded data during an input phase of a turbo decode operation. An address generator generates the regenerated interleaver sequence based on the column indexes and computed data. In embodiments the address generator can read column indexes from the addressable column index memory, compute the computed data by permuting row indexes in a same row permuting order as an encoder that encoded the encoded data, combine the column indexes so read and the row indexes so permuted, use a row counter, and identify out of bounds addresses using the regenerated interleaver sequence.
A mobile cellular radio device including a turbo decoder for decoding encoded data, comprising:
A method of decoding encoded data performed by a mobile cellular radio device that includes an antenna, a radio receiver coupled to the antenna and configured to receive and demodulate a signal from the antenna to produce the encoded data, one or more processors coupled to the radio receiver and configured to decode the encoded data, and an addressable column index memory, the method performed by the one or more processors comprising the steps of:
