| Abstract(in English) | We propose a sequentially-updated channel estimation (SUCE) to realize a robust SDM-OFDM system against a fast-variant fading condition. The proposed SUCE consists of (i)replica symbol generator, (ii)co-channel interference (CCI) canceller, (iii)instantaneous channel response estimator, (iv)channel degradation detector, and (v)average unit. In addition to the proposal of SUCE, we consider a configuration of SDM-OFDM receiver with SUCE and a multiple-QR-decomposition (Multi-QRD) based signal detection that we have already proposed. Then, we also refer to the advantage of the receiver from viewpoint of a latency time in signal processing. In this paper, we show the effectiveness of the proposed SDM-OFDM receiver in a fast-variant fading condition through computer simulation. |
