Modelling and Analysis of Non-Stationary Multipath Fading Channels with Time-Variant Angles of Arrival
Pätzold, Matthias Uwe; Gutierrez, Carlos Adrian (Chapter; Peer reviewed, 2017)In mobile radio channel modelling, it is generally assumed that the angles of arrival (AOAs) are independent of time. This assumption does in general not agree with real-world channels in which the AOAs vary with the ... -
