This paper proposes a parametric channel estimation method for massive multiple input multiple output (MIMO) systems, whereby the spatial correlation of wireless channels is exploited. For outdoor communication scenarios, most wireless channels are sparse. Meanwhile, compared with the long signal transmission distance, scale of the transmit antenna array can be negligible. Therefore, channel impulse...
With the increasing of the traffic of the civil aircrafts, the broadband aeronautical communications are required. Different from the narrow-band system, the broadband system for Air-to-Ground (A/G) communications bases on the broadband non-continuous spectrum located in VHF and L band, which are traditionally occupied by radar systems, such as Distant Measurement Equipment (DME) etc. Therefore, it...
