A frequency diplexer network for ultrawideband radios focused on wireless parallel data transmission is presented. It has a combination of two bandpass filters utilizing manifold multiplexing technique. In the frequency band 6–9 GHz, two flat sub‐bands at center frequencies 6.7 and 8.3 GHz have been achieved with respect to forward transmission, input reflection, and group delay. A maximum group delay variation of 0.6 ns was measured in the sub‐bands. For low cost and simple circuit implementation, the design is implemented using the microstrip technology. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1869–1871, 2014

“…At the physical layer (PHY), Orthogonal Frequency Division Multiple Access (OFDMA) is beginning to be considered as the best solution for some 4th Generation (4G) wireless networks. Worldwide Interoperability for Microwave Access (WiMAX), defined by the IEEE 802.16 standard [1] and other multicarrier-based equipment like Long Term Evolution (LTE) systems [2] are examples of emerging OFDMAbased technologies. OFDMA enable the system to allocate spectral resources in an efficient and flexible way, due to the partial usage of time and frequency domains for several users.…”

Abstract. Orthogonal Frequency Division Multiple Access (OFDMA) is one of the most promising, demanded and researched modulation and access methods for future mobile wireless networks. Emerging technologies, like Worldwide Interoperability for Microwave Access (WiMAX) or Long Term Evolution (LTE), are adopting OFDMA due to its high spectral efficiency, scalability for high amounts of users and mobility support. In OFDMA, before data is actually transmitted, it must be mapped into a time-frequency matrix through a resource allocation process. This step is critical for a correct network behaviour, and several factors must be taken into account like efficiency, Quality of Service (QoS) fulfillment or power consumption. In this paper, we propose a novel approach for the mapping process of IEEE 802.16e networks, and we compare its performance with several existing algorithms. The effectiveness of our proposal is evaluated in different scenarios by means of extensive simulation.

A new scheme of antenna for wireless body area networks is proposed. A coupling‐fed circular‐patch antenna with TM01 mode is designed, simulated, and tested, which radiates omni‐directional pattern along the body surface and has linear polarization normal to the surface. Both simulated and measured results show this antenna satisfies the expected 9% bandwidth (5.725–5.875 GHz) for return‐loss ≤ −10 dB, and it is suitable for on‐body communication application. © 2009 Wiley Periodicals, Inc.
