| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In a massive multiple-input multiple-output (MIMO) system based on time division duplex (TDD), the channel state information (CSI) between the base station (BS) and the user terminal (UT) is required. Due to Doppler shift, the fluctuations of the channel between the BS and the UT causes differences of the channel between the channel estimation and channel utilization, which is an issue called channel aging. In this report, we propose a data-aided channel estimation method based on deep learning to mitigate the effect of channel aging in a massive MIMO system with pilot contamination. After signal detection using the estimated channel obtained from the received signal in the pilot part, the detected symbol is regarded as a pilot and the channel for each time slot is estimated from the received signal in the data part. Through computer simulations, we show that the proposed method improves the channel estimation accuracy compared with the deep learning-based channel estimation with received pilot signal and the interpolation method. | |
