| Abstract(in English) | When a MIMO system is introduced in a cellular system, we have to measure the received power from all the connectable base station (BS), as well as to identity all the CSI for the combination of transmitter and receiver antenna elements. One of the most typical channel estimation scheme is to employ a code division multiplexing (CDM) based scheme in which a unique spreading code is assigned to identify both BS and MS antenna elements. However, with increasing the number of transmit antenna elements, a large spreading code and pilot symbols are required to estimate an accurate CSI. To reduce this problem, the carrier interferometry (CI)-SDM/OFDM has been proposed. However, each detected channel impulse response is affected by the noise without noise whitening. Therefore, the pilot signal averaging process for multi-slot is necessary for improving the accuracy of CSI. As a result, the transmission rate is degraded due to a large number of pilot symbols transmission. To reduce these problems, hi this paper, we propose a high time resolution carrier interferometry (HTRCI) for SDM/OFDM to achieve an accurate CSI without increasing the number of pilot symbols. |
