ERROR | CORRECTION |

1) Equation (D.5b) reads | 1) Equation (D.5b) should read as |

ERROR | CORRECTION |

2) Figure 2.38 has the wrong x-axis labels, though the curve is correct. | The correct and complete replacement for Figure 2.38c is here: |

ERROR | CORRECTION |

3) The discussion on signal order for OFDM on page 208 is not consistent with conventional use. And Figure 7.22 needs to be replaced. | Signal Order of OFDM Even though the individual OFDM subcarriers may be QAM modulated with simple low-order constellations, the number of information bits that the entire OFDM symbol carries will get very large when many subcarriers are used. The order of the entire OFDM signal is equal to the count of the total signal states available to the OFDM signal. This is an identical definition of signal order to that used in all other previous signals. Assuming that all OFDM subcarriers are carrying data we write the order as here. |
