Twin-stack decoding of recursive systematic convolutional codes.

Twin-stack decoding of recursive systematic convolutional codes.

We present a method for soft-in/soft-out sequential decoding of recursive systematic convolutional codes. The proposed decoder, the twin-stack decoder, is an extension of the well-known ZJ stack decoder, and it uses two stacks. The use of the two stacks lends itself to the generation of soft outputs...
