Capacity of Nakagami- $m$ Fading Channel With BPSK/QPSK Modulations

In this letter, we develop a recurrence formula for the capacity of Nakagami-m fading channel with BPSK/QPSK modulations when channel state information is available at the receiver. For each fading parameter m, a simply constructed series representation with a fast-convergence rate can be obtained through the recurrence formula. The series expansion provides a numerically efficient way to calculate the capacity for both Rayleigh and Nakagami-m fading channels. The simulation results show that the recurrence formula is a good alternative for estimating the capacity of Nakagami fading channel.
