Description: In this paper, the problem of estimation
of fast time-varying radio channels is considered. A
new algorithm, Iterative Channel Estimation is
presented. This algorithm is designed for radio
channel estimation in multiple-input multipleoutput
systems with space-time block coding. The
channel transfer matrix is estimated on the basis of
a previously decoded data, so it can be performed
simultaneously with the data transmission. The
estimation process is a simple operation, just a
multiplication of two matrices. As a result, bit error
rate is reduced. The algorithm is compared to the
differential space-time block codes and verified by
Monte-Carlo simulations. Platform: |

Description: MIMO stands for Multiple-input multiple-output. While it involves multiple technologies, MIMO can essentially be boiled down to this single principle: a wireless network that allows the transmitting and receiving of more than one data signal simultaneously over the same radio channel. Standard MIMO networks tend to use two or four antennas. Massive MIMO, on the other hand, is a MIMO system with an especially high number of antennas. Platform: |

Description: Channel estimation for millimeter-wave (mmWave)
massive MIMO with hybrid precoding is challenging, since the
number of radio frequency (RF) chains is usually much smaller
than that of antennas. To date, several channel estimation schemes
have been proposed for mmWave massive MIMO over narrowband channels, while practical mmWave channels exhibit the
frequency-selective fading (FSF). To this end, this letter proposes
a multi-user uplink channel estimation scheme for mmWave
massive MIMO over FSF channels. Specifically, by exploiting the
angle-domain structured sparsity of mmWave FSF channels, a
distributed compressive sensing (DCS)-based channel estimation
scheme is proposed. Moreover, by using the grid matching pursuit strategy with adaptive measurement matrix, the proposed
algorithm can solve the power leakage problem caused by the
continuous angles of arrival or departure (AoA/AoD). Simulation
results verify that the good performance of the proposed solution. Platform: |
