Receiver Sensitivity of 2Rx-1Tx system - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2010 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

How do we calculate the Receiver sensitivity for a system employing 2 receivers and 1 transmitter. Do we have any formula for calculating the sensitivity or SNR improvement analogus to 1RX-1 Tx system.

SNR improvement will depend on the way in which the 2 Rx's are combined - switching diversity, equal gain combining or maximal ratio combining. A good place to start would be the book by Rappaport (Wireless Communications). The book goes through a simple SNR calculation for each of the three cases.
