A multiple code-rate turbo decoder based on reciprocal dual trellis architecture

To increase channel efficiency for high throughput systems, the high code-rate schemes are usually required. However, conventional turbo decoders in high code-rate usually apply high radix trellis structure, and the complexity of the trellis increases exponentially according to the code-rate. In this paper, the reciprocal dual trellis is applied to reduce the trellis complexity and a multiple code...
