| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Frequency-domain equalization is well known as a countermeasure for inter-symbol interference in a single carrier transmission system in terms of light weight and reasonably high performance. Frequency-domain turbo equalization with iterative processing has been developed as the extension to provide very high performance. In this paper, we consider a channel equalizer using a belief propagation (BP) algorithm in the time domain. In multiple-input multiple-output multi-path environments, it has been reported that this algorithm achieves a near-optimum BER performance. However, in single-input single-output (SISO) multi-path environments, the normal BP algorithm does not work. We show the problems and a solution against that. And we evaluate the BER performance with our proposal in a SISO multi-path environment. | |
