Norbert WehnTalk Title: When Channel Coding hits the Implementation Wall


The continuous demands to higher throughput in communications systems, in addition to higher spectral efficiency and lowest signal processing latencies, leads to throughput requirements for the digital baseband signal processing far beyond 100Gbit/s. This is one to two orders of magnitude higher than the tens of Gbit/s targeted in the 5G standardization. At the same time, advances in silicon technology due to shrinking feature sizes and increased performance parameters alone won’t provide the necessary gain, especially in energy efficiency for wireless transceivers, which have tightly constrained power and energy budgets. The focus of this talk lies on channel coding that is a major source of complexity in digital baseband processing. We will highlight implementation challenges for the most advanced channel coding techniques, i.e. Turbo-Codes, LDPC codes and Polar codes, and discuss approaches to tackle these challenges.
