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

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the 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.
