SNR / BER / PER Calculation

  • By tracking other signals received, Interference is estimated. The decision will be taken, by the power of computing interference for packets. 
    • Successful or failed reception will be calculated in receiving packets. The chances of success or failure were determined by interference signal and modulation of the packet.
    • The total number of bit errors divided by the total number of bits transferred is known as the Bit error rate. By using various modulations, SNR- BER tables will be evaluated.
    • Losses in transmitting powerless RF propagation are estimated by the strength of received signals. The losses of propagation add Fading, Shadowing, and Pathloss.
