Rooftop and indoor reception with transmit diversity applied to DVB-T networks: A long term measurement campaign [PDF]
, 2009 Although transmit Delay Diversity (DD) can provide a gain in indoor and other Non Line of Sight situations (NLOS), it can introduce degradation in rooftop reception. In fact, when the Ricean K factor of the channel is significantly high (e.g.

Closed Form Approximations for UAV Line-of-Sight Probability in Urban Environments
IEEE Access, 2023 This paper presents a new approach to estimate the probability of line-of-sight (LoS) for unmanned aerial vehicle (UAV) communications. We provide lower and upper bounds on the probability of LoS in terms of what we call the first-building-LoS ...
