A well-known practical application of diversity reception is in wireless microphones, and in similar electronic devices such as wireless guitar systems. A wireless microphone with a non-diversity receiver (a receiver having only one antenna) is prone to random drop-outs, fades, noise, or other interference, especially if the transmitter (the wireless microphone) is in motion.

WebbDefinition: Fading in wireless communication is defined as the fluctuation in the strength of the signal received at the receiver. These are basically unwanted variations introduced at the time when the signal propagates from an end to another by taking multiple paths.

Webb1 Answer. Diversity is a powerful communication receiver that provides wireless improvement at relatively low cost. It requires no training overhead since a training sequence is not required by the transmitter. Diversity exploits the random nature of radio propagation by finding independent signal paths for communication.
