Diversity gain in wireless communication

WebDiversity gain. In wireless communication system, diversity gain is the increase in signal-to-interference ratio due to some diverse schemes i.e. or how much the transmission power can be reduced when a diversity scheme is introduced without a performance loss factor. Diversity gain is usually expressed in dB and sometimes as a power ratio. Webantenna array. Array gain improves resistance to noise, thereby improving the coverage and the range of a wireless network. Spatial diversity gain As mentioned earlier, the signal level at a receiver in a wireless system fluctuates or fades. Spatial diversity gain mitigates fading and is realized by providing the receiver with
