In this paper, we propose an efficient architecture based on pre-computation for Viterbi decoders incorporating Talgorithm. Through optimization at both algorithm level and architecture level, the new architecture greatly shortens the long critical path introduced by the conventional T-algorithm. The design example provided in this work decomputation overhead while maintaining decoding performancemonstrates more than twice improvement in clock speed with negligible.

Sure, most of you are aware that right now everyone is thinking or at least the industry and researchers are thinking about the next generation, the first generation of what will 5G be, and that a significant part of the 5G telecommunication standard has been finalised, in particular the error control codes that will be used in 5G telecommunication. One of the codes that will be used is called a Low-Density Parity Check code (or LDPC code for short), and the other is called Polar Code. These two famous and celebrated codes have distinct and fascinating histories. Both technologies are now capable of providing near-capacity results, making them formidable competitors in the race to become the 5G communication system's ultimate provider. In this paper, we zeroed in on the 5G Polar codes and their encoding methods.
