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.
