With the active evolvement of 3GPP long term evolution (LTE) system, advanced multi-user multiple-input multiple-output (MU-MIMO) transmission schemes attract more and more interests in engineering field. However, in order to bring advanced MU-MIMO techniques from theory to practice, there are two major obstacles to overcome, i.e., how to obtain accurate channel state information at the transmitter...
Adding into the cluster of available detection schemes designed for scenarios where user terminals are highly mobile, this paper describes a semi-self-recovery OFDM signal detection method for rapidly time-varying channels. The proposed algorithm does not assume the channel status information (CSI) at the receiver, it tracks the channel variation while detecting the data symbols. The key feature of...
