“…Since the US Federal Communications Commission agreed to allocate a frequency band of 7.5 GHz for ultra‐wideband (UWB) communications in February 2002, UWB technology has been a promising candidate for short‐range high‐speed wireless transmission . In general, there are two competing high data rate UWB approaches, namely the direct sequence impulse radio and the multiband orthogonal frequency division multiplexing (MB‐OFDM) . MB‐OFDM approach that is expected to offer data rates up to 480 Mb/s has received considerable attention because of its ability to reduce radiofrequency interference and multipath effects at a relatively low cost.…”

Summary ECMA‐368 Standard adopts multiband orthogonal frequency division multiplexing (MB‐OFDM) for high rate ultra‐wideband (UWB) communication systems as a possible candidate for indoor wireless personnel area networks. One of the main drawbacks of MB‐OFDM modulation is the high peak‐to‐average power ratio (PAPR), which limits the power efficiency of the digital‐to‐analog converter and the high power amplifier due to nonlinear distortion. In this paper, a post inverse discrete Fourier transform nonlinear transformation called parametric discrete sliding norm transform (PDSNT) is proposed to reduce the PAPR in MB‐OFDM systems. The PDSNT method in addition to its much lower computational complexity than other schemes recently proposed for ECMA‐368 UWB systems introduces an efficient controlling parameter to obtain a good tradeoff between PAPR reduction and bit error rate (BER) performance degradation. Simulation results show that the proposed PDSNT‐based MB‐OFDM scheme can achieve better performance in PAPR reduction than conventional solutions with affordable BER performance degradation in UWB channel models.

“…Ultra-wideband (UWB ) technology used in wireless communication systems has been widely investigated for its low cost, high data transmission rates, low power and acceptable physical implementation [1]- [3]. In UWB two high data rate techniques are possible, direct sequence UWB (DS-UWB) [4] and multiband orthogonal frequency division multiplexing (MB-OFDM) [5] [6]. MB-OFDM, which is supposed to deliver data speeds of up to 480 Mb/s, gained significant interest due to its potential to minimize multipath and radio frequency interference effects [7] [8], it has been oriented to differentes standards such as IEEE 802.15.3a and ECMA-368 [5] [6].…”

A multiple-input-multiple-output (MIMO) ultra-wideband (UWB ) printed bent antenna, suitable for MB-OFDM ECMA-368 system integration with the wireless universal serial-bus (WUSB) dongle is proposed. The antenna consists of two antenna elements with an overall area of 18 X 53 mm2. Each antenna element is a simple modified folded-monopole fed by a coplanar waveguide (CPW). The design process of proposed MIMO UWB CPW-fed bent antenna configuration is presented in four simple steps. Experimental results show that the proposed design has a good impedance bandwidth in the range of 2.95–18.55 GHz with 147.2% fractional bandwidth (FBW). Moreover, the proposed antenna enjoys, low envelope correlation coefficient (ECC), good diversity gain (DG), low total active reflection coefficient (TARC) and omnidirectional radiation patterns. The bit error rate (BER) of the overall MB-OFDM ECMA-368 system with the existence of the proposed MIMO UWB CPW-fed bent antenna is evaluated in more realistic transmission channel scenario by using the extracted transmitting and receiving UWB antennas transfer functions.
