BER

Mathematical Analysis

Mathematical Analysis

The BER of the QDPSK:

,

In the representation of the equation above,

,

Which is the pdf of the output SNR. L is the channel number.

,

 

,which is the Marcum Q-function.

 

the BER performance of QDPSK with postdetection diversity reception over Nakagami

fading and AWGN can be expressed in the form, which seems complex .

 

From which, we can get the numerical results of the BER.
