Abstract:
1. A method for terminating two constituent encoders of a turbo encoder employing a turbo code, the method compromising: generating tail output bits associated with a turbo code rate (R) in each of the two constituent encoders after at least one of the two constituent encoders encodes information bits, wherein each of the two constituent encoders comprises a first shift register having a first output that is connected to a second shift register having a second output that is connected to a third shift register having a third output, wherein a first set of the tail output bits is generated in a first of the two constituent encoders from the second and third outputs of the second and third shift registers of the first of the two constituent encoders while a second of the two constituent encoders is disabled and a second set of the tail output bits is generated in the second of the two constituent encoders from the second and third outputs of the second and third shift registers of the second of the two constituent encoders while the first of the two constituent encoders is disabled.
