What is RAKE RECEIVER and its Purpose in CDMA

Rake Receiver Instead of trying to overpower or correct multipath problems, CDMA takes advantage of the multipath to improve reception quality in fading conditions. CDMA does this by using multiple correlating receivers and assigning them to the strongest signals.  This is possible because the CDMA mobile is synchronized to the serving base station. The mobile’s … Read more

Basic RF Propagation Models for LTE

An RF propagation model is a mathematical formula used to characterize the radio is Wave transmitter at one end and the other end into the receiver propagation between It is usually a path RF frequency, distance, antenna heights of the terrain, Clutter and other conditions. It’s all in the exact damage to telecommunication systems is … Read more

How to Control Inter-System Interference in LTE

The Various steps to control inter-system interference include: 1. external Filters, add the transmitters and receivers 2. Antenna isolation between transmitters and receivers of victims 3. the distance between transmitters and receivers of victims 4. Reduce transmission power 5. Guard band between operators Step 1 is probably the most common technical solutions. This can have … Read more
