“…The multi-carrier OFDM scheme has fostered the rise of several wireless and wired communication standards including: Digital Broadcasting of Audio and Video contents, in Terrestrial and Handheld scenarios (DAB, DVB-T/H) (see [6,22]); 802.16-d/e Wireless Metropolitan Area Network (WMAN), known respectively as fixed and mobile WiMAX [17], for wireless fast Internet access in metropolitan scenarios; xDSL [7,12,31,41] and BPL [1,3,11] modem for fast Internet access through wired channels, the telephone line and the power line respectively; 802.11 a/n WLAN for medium range indoor networking [20,26,38]; UWB radio [18,32,36] for high data rate personal area network connectivity. The connectivity range covers short range using UWB radio, mid range based on WLAN, BPL and VDSL and wide range through DVB-T/H, DAB, WMAN and xDSL standards.…”

“…The different OFDM standards considered in this paper (UWB, WLAN 802.11 a/n, WMAN 802.16 d/e, DVB-T/H, DAB, VDSL, BPL) are characterized by different requirements for the FFT/IFFT processing in terms of I/O data-width, from 4 to 16 bits, transform length, from 64 to 8192 points, and throughput, from 1 MSamples/s to several 1 GSamples/s (see [1,6,11,12,17,18,20,22,38,41]).

The design of Fast Fourier Transform (FFT) integrated architectures for System-on-Chip (SoC) telecom applications is addressed in this paper. After reviewing the FFT processing requirements of wireless and wired Orthogonal Frequency Division Multiplexing (OFDM) standards, including the emerging Multiple Input Multiple Output (MIMO) and OFDM Access (OFDMA) schemes, three FFT architectures are proposed: a fully parallel, a pipelined cascade and an in-place variable-size architecture, which offer different trade-offs among flexibility, processing speed and complexity. Silicon implementation results and comparisons with the state-of-the-art prove that each macrocell outperforms the known works for a target application. The fully parallel is optimized for throughput requirements up to several GSamples/s enabling Ultra-wideband (UWB) communications by using all channels foreseen in the standard. The pipelined cascade macrocell minimizes complexity for large size FFTs sustaining throughput up to 100 MSamples/s. The in-place variable-size FFT macrocell stands for its flexibility by allowing run-time reconfigurability required in OFDMA schemes while attaining the required throughput to support MIMO communications. The three architectures are also compared with common case-studies and target technology

“…However, WLAN lack in mobility and can be used only in small area around 'hot spot'. On the other hand, WMAN (Wireless metropolitan area network) provides mobility and larger area of coverage than WLAN at lower data rate [4]. WLAN/WMAN dual-mode transceiver can provide both mobility and data rate to fulfill explosive demand in wireless devices.…”

WLAN(IEEE 802.11a)/WMAN(IEEE 802.16a) dual mode transceiver chip has been proposed, designed and fabricated. Transceiver RF IC chip with packaged size of 6mm*6mm was fabricated using 0.25 um SiGe BiCMOS process. Power amplifier and PLL/VCO chip were fabricated using the same process. Ceramic front-end filter were also fabricated for WLAN/WMAN frequencies. To make compact transceiver system, these chips was mounted on 2 cm*2 cm double side PCB.The full system has been tested with external ADC/DAC and baseband modem. The measured results show that fabricated transceiver system meets the requirements for WLAN/WMAN standards. Index Terms-WLAN/WMAN, dual mode, transceiver system, RF IC

Emerging standards in the area of mobile services, such as Worldwide Interoperability for Microwave Access (WiMAX) and Universal Mobile Telecommunication System (UMTS), require new capabilities from mobile devices. As a result, these devices should know how to download and correctly install reconfigurable modules. For this purpose, the Software Defined Radio (SDR) technology is used at present. SDR allows co-existence of different independent standards, protocols, and services. This signal processing approach is widespread due to the great importance of reprogramming and reconfiguring of mobile devices. Because of the availability of SDR technique in device architecture, a user can update and replace necessary services without changing hardware. In this paper, we present a new solution of SDR implementation for UMTS/WiMAX system. Furthermore, we consider common blocks in our system in detail and demonstrate the implementation of the framework model in object-oriented style using SystemC.
