What is meant by achieving "full diversity gain over Rayleigh fading channel"?
Diversity gain refers to the improvement in signal quality and reliability that can be achieved through the use of multiple antennas or paths in wireless communication systems. It allows for better coverage, increased data rates, and reduced interference.
Diversity gain is typically measured in decibels (dB) and is calculated by comparing the signal quality with and without diversity techniques. The higher the diversity gain, the better the signal quality and reliability.
There are several types of diversity gain, including spatial diversity, temporal diversity, frequency diversity, and polarization diversity. These techniques use different methods to exploit the diversity of the wireless channel and improve signal quality.
Some examples of diversity techniques include multiple-input multiple-output (MIMO) systems, which use multiple antennas at both the transmitter and receiver to improve signal quality, and receive diversity, which uses multiple antennas at the receiver to improve reliability.
The main benefits of diversity gain include increased coverage and range, improved signal quality and reliability, and higher data rates. This can lead to better overall performance and user experience in wireless communication systems.
