Iridium system employs a BPSK modulation and forward error correction coding in the form of convolutional encoding with Viterbi decoding (Viterbi 1971).
Signal constellations for BPSK modulation scheme at the phase offset of 20[degrees] in the uplink and the downlink are shown in figure 5 (distortions are caused by HPAs and phase offset), and the frequency offset in the uplink and the downlink at 2 Hz is provided in figure 6 (distortions are caused by HPAs).
16 fixed Wimax standard, six transmission modes along with new modulation of BPSK are considered.

11a/g features are supported including data scrambling, forward error-correction via convolutional encoding at rates from 1/2 to 3/4, sub-channel coding of BPSK, QPSK, 16QAM or 64QAM, both short- and long-training sequences, pilot insertion, and the IFFT/FFT required to convert to/from time-domain RF I/Q signals.
According to Sklar (Sklar, 2002), turbo codes were first introduced in 1993 by Berrou, Glavieux, and Thitimjshima achieving a bit-error probability of 10-5 using a rate 1/2 code over an additive white Gaussian noise channel and BPSK modulation at an [E.
Each narrowband subcarrier can be modulated using various modulation formats; BPSK, QPSK and QAM (or differential equivalents).
