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.
