Publisher：IEEE

We have developed a web-based survey system cooperating with the authentication server of the university. This system has functions to enhance institutional research, such as displaying response rates by each departments of the university. The present study provides an overview and a case study of the use of this system.

IEICE TRANSACTIONS ON FUNDAMENTALS OF ELECTRONICS COMMUNICATIONS AND COMPUTER SCIENCESE98A ( 11 ) 2254 - 2262 2015.11Achievement Accurate CSI for AF Relay MIMO/OFDM Based on Complex HTRCI Pilot Signal with Enhanced MMSE EqualizationReviewed

Publisher：IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG

Amplify-and-forward (AF) relay multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems can achieve high data rate and high quality communications. On the other hand, it has to estimate all channels between the source-relay and relay-destination nodes in the destination node. In MIMO/OFDM systems, high time resolution carrier interferometry (HTRCI) has been proposed to achieve an accurate channel estimation (CE) with a small number of pilot signals. However, since it has many interferences, an accurate CE is not obtained and the system performance is degraded in AF relay MIMO/OFDM systems. Therefore, in this paper, we propose the complex HTRCI (C-HTRCI) pilot signal and the enhanced minimum mean square error (E-MMSE) equalization to achieve an accurate CE and to improve the system performance for AF relay MIMO/OFDM systems.

Yuta Ida, Kota Imafuku, Takahiro Matsumoto, Shinya Matsufuji . Performance Evaluation for AF Relay TFI-OFDM Systems . 2015 INTERNATIONAL SYMPOSIUM ON INTELLIGENT SIGNAL PROCESSING AND COMMUNICATION SYSTEMS (ISPACS) ( 3D-4 ) 548 - 551 2015.11Performance Evaluation for AF Relay TFI-OFDM SystemsReviewed

Publisher：IEEE

Amplify-and-forward (AF) relay transmissions can achieve a low power long distance communication. The problem of the AF method is that the channel state information (CSI) between source-relay (SR) and relay-destination (RD) should be obtained simultaneously in the destination node. The pilot signal is inserted to obtain the CSI, and the time frequency interferometry (TFI) method can reduce the number of pilot signals and the channel estimation (CE) power. This paper proposes the low power CE for AF relay transmissions in an orthogonal frequency division multiplexing based on the TFI method.
