SUMMARY
The discussion focuses on calculating the probability of error in an adaptive modulation system using specific modulation schemes: PQPSK, P16QAM, and P64QAM. The values derived are PQPSK = 0.502368, P16QAM = 0.0526855, and P64QAM = 0.000004, with a noise probability Pno = 0.4450. The calculations involve converting values from dB and utilizing the integral formula -exp(gamma/gamma_bar) evaluated from a to b, leading to results of 0.413505, 0.402453, and 0.0293970 for different parameters.
