Performance Analysis of Non- Coherent FSK System with Square Law Combining our Nakagami- m Fading Channel

The probability of error for NFSK with square law combining for diversity correlated Nakagami channels is analyzed. The closed for of expression using characteristic function is derived. The average SNR per branch is considered to be distinct. The effect of different noise powers for various diversity orders and fading channel parameters on probability of error and unequal SNR distribution is being studied. All calculation has been made for total SNR and the average SNR for each diversity branch is achieved from total SNR. [9]
