Forward Error Correction (FEC)

The FEC is usually given as a fraction

$$ Number \space of \space useful \space bits \space \div Total \space number \space of \space bits $$

For our per frame overhead, we have

$$ datarate = R_sM $$

Where $R_s$ is symbol rate and $M$ is number of bits per symbol (1, 2, or 3 for BPSK, QPSK, and 8PSK)

Transmitter usually has a roll-off of

$$ \alpha = 0.2 $$

$$ f_c = [2200,2290] [MHz] $$

$$ Rs = [100,5000] [kBd] $$

$$ P_T = [20,33] [dBm] $$

we will be operating at 33 dBm CONSTANTLY

Occupied bandwidth 99.0% = $1.07R_s \space [Hz]$
