Method for a general turbo code trellis termination

摘要

The present invention relates to a method for terminating two or more constituent encoders of a turbo encoder employing a turbo code, the method comprisig the steps: generating tail input bits at each of two or more constituent encoders by deriving the tail input bits from each of the two or more constituent encoders separately for each constituent encoder from a contents of shift registers within each of the two or more constituent encoders, after an encoding of information bits by the two or more constituent encoders; transmitting tail output bits from a first X(t) output branch and from a second Y 0 (t) output branch during trellis termination of a first of the two or more constituent encoders; and transmitting tail output bits from a third X' (t) output branch and from a fourth Y 0 '(t) output branch during trellis termination of a second of the two or more constituent encoders. The invention also relates to a system for performing this method.
