We consider channel estimation for high-speed railway communication systems, where both the transmitter and the receiver are equipped with large-scale antenna arrays. It is known that the throughput of conventional training schemes monotonically decreases with the mobility. Assuming that the moving terminal employs a large linear antenna array, this paper proposes a position-aided channel estimation...
Channel estimation is a major overhead factor in large-scale multiple-input multiple-output \mbox{(MIMO)} systems, especially under the high- speed railway scenarios. This paper proposes a position-aided channel estimation scheme for high- speed railway communication systems, where both the transmitter and the receiver are equipped with large-scale antenna linear arrays. By joint spatio- temporal...
In this paper, we consider a topology composed of two correlated source nodes and one aggregation node. Discrete i.i.d samples of each source are assumed. To take advantage of the correlation between two sources, we propose an asymmetric compression scheme, which is motivated by typical set deterministically rather than probabilistically. Block fading and AWGN are assumed for the both source-destination...
