An application of block codes to turbo equalization

Abstract (in Japanese) (See Japanese page) 
(in English) In mobile communications, the signal quality is often degraded due to multipath fading. However, a demand for a high-data-rate and a large capacity is growing even in the mobile communication. In this paper, to achieve the higher data-rate mobile communication, we propose a turbo equalization with multilevel block-coded modulation (BCM). The turbo equalization has an excellent ability of equalization and the BCM can comparatively make the transmission rate high and the calculation cost low. We combine these techniques and investigate the transmission characteristics. And then, we investigate an improvement of BER performance of a turbo equalization using LDPC code. In order to raise the convergence property of the turbo equalization using LDPC code, we apply SC/MMSE (Soft Cancelling with MMSE), and the BER performance is improved by exchanging information by an ISI equalizer and SC/MMSE.
