Proposals to build a promising ultra-wideband wireless communications

Abstract

The variants of constructing promising ultra-wideband wireless communications systems based on the new standard. This standard specifies an ultra wideband (UWB) physical layer for a wireless personal area network (PAN), utilizing the unlicensed 3100 – 10600 MHz frequency band, supporting data rates of 53.3, 80, 106.7, 160, 200, 320, 400, 480, 640, 800, 960 and 1024 Mb/s. This standard specifies a Multi Band Orthogonal Frequency Division Modulation (MBOFDM) scheme to transmit information. A total of 110 sub-carriers (100 data carriers and 10 guard carriers) are used per band to transmit the information. Frequency-domain spreading, time-domain spreading, modulation and forward error correction (FEC) coding are used to vary the data rates.
