What is two ray model in wireless communication?
The two-rays ground-reflection model is a multipath radio propagation model which predicts the path losses between a transmitting antenna and a receiving antenna when they are in line of sight (LOS). Generally, the two antenna each have different height.
What is a MIMO layer?
Single-user MIMO (SU-MIMO) is the ability to transmit one or multiple data streams, called layers, from one transmitting array to a single user.
How does MIMO increase capacity?
MIMO is an antenna technology, which was first proposed by Marconi in 1980. It improves the capacity and data transmission rate of the communication system by connecting multiple antennas at the transmitter and the receiver.
What is critical distance in wireless communication?
The critical distance dc, is the distance after which the signal power falls off proportionally to d−4. An approximation for dc can be obtained by setting ∆φ = π ⇒ dc = 4hthr /λ, The critical distance dc can be used for system design.
