Abstract

Turbo coding has reached a great interest in the last years. It offers better performance than most of the traditional coding schemes. Turbo coding has been considered for using in the next mobile communications standard (IMT-2000). For decoding of these codes a soft-input-soft-output (SISO) decoder is necessary. Several reduced complexity algorithms suitable for hardware implementation have been introduced. However, a comparison in terms of performance, throughput, complexity and power consumption is not available. In this paper different turbo decoder algorithms and architectures are compared in this aspects with focus on the proposed parameters of IMT-2000.
