UWB Modulation Schemes

Abstract

To be considered ultra wideband (UWB) per FCC definition, a signal must satisfy one of the two frequency domain requirements as stated in Chap. 1. One family of signals that satisfy the UWB requirements are impulse radios. There are, however, a number of others. Impulse radios were treated in Chaps. 3 and 4. In this chapter, we introduce other UWB modulation types such as frequency hopping (also known as multiband) and direct sequence approaches.

Notes

  1. 1.

    http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=53426

  2. 2.

    The OFDM symbol period must be significantly less than coherence time of the channel to avoid ICI.

  3. 3.

    Subcarrier bandwidth must be much larger than the channel Doppler spread.

  4. 4.

    DCM is a four-dimensional modulation scheme.
