How and What Spatial Diversity Antenna Systems in GSM The spatial diversity antenna system is constructed by physically separating two receiving base station antennas. Here I write on spatial diversity…
Diversity Reception: Multiple Antennas at Base Station Each Antenna is Affected by Multipath Differently Due to Their Different Location Allows Selection of the Signal Least Affected by Multipath Fading If…
Time diversity is a technique common to most digital transmission systems. The Rake Receiver is used to find and demodulate multipath signals that are time delayed from the main signal….
Spatial Multiplexing In a multipath environment, the data rate increase due to MIMO is equal to the number of MIMO antennas. Rather than to transmit the same bit of more…
Make use of a number of receive antennas that are well separated (coherence distance) to generate independent receptions of the transmitted signal. Selection diversity: choose received signal with largest received…
We know that we normally have several independent paths from TX to Rx of different lengths, these are affected and delayed differently, Signals that start out together at the transmitter…
Here I write down which point to tack care during antenna installation which including Wind load, Work Temperature and Humidity and Camouflaged Antenna Scheme for Sites Wind Load The antennas…
Here I write down some passive characteristics definition for antenna which include Port Isolation, Power capacity, Input Port of Antenna, Passive Intermodulation (PIM) and Dimensions and Weight of Antenna. For…
Any Antenna may be Omni antennas or Directional antenna. Omni antennas provide approximately the same amount of profit throughout the entire 360-degree horizontal pattern. Directional antenna, sometimes referred to as…
