Abstract
Terrestrial Trunked Radio (TETRA) is a digital trunked mobile radio standard developed by the European Telecommunications Standards Institute (ETSI). Especially, TEDS (TETRA Enhanced Data Services), part of TETRA Release 2, supports different channel bandwidths and modulation techniques, and turbo code has been adopted as a channel code with powerful error correcting capability. Due to its inherent high complexity and long latency of turbo code, the implementation of high-performance turbo decoder requires optimizations in various design levels. In this paper, we present the algorithmic modifications for low-complexity hardware implementation, architectural solutions and several optimizations for high-performance TEDS-compatible turbo decoder.
