“…The use of FPGA platforms to accommodate the OFDM transmitters of both IEEE 802.11a and 802.16-2004 standards was addressed in [49,50]. The implementation of individual parts of OFDM transceivers, such as FFT and its inverse [51,52], a peakto-average power ratio (PAPR) reduction [53], an interleaving [54], a higher-order square M Quadrature amplitude modulation (QAM) detection/demodulation [19], a 64-QAM demodulator [55], a channel error detection and correction [56], and baseband transmitter [57,58] have been investigated so far. Overall, these contributions show the suitability, flexibility, and abundance of resources of FPGA platforms, such as lookup table (LUT), memory, multipliers, and other intellectual property (IP) for designing high-speed and reconfigurable transceivers.…”

Aiming at reducing hardware complexity and power consumption of multicarrier-based broadband transceivers, this contribution discusses and analyzes the implementation of clustered-orthogonal frequency division multiplexing (OFDM)-based transceiver in a field programmable gate array (FPGA) device. In this sense, several OFDM schemes covering baseband and passband data communications are implemented. The hardware resource utilization and power consumption related to each scheme, after being implemented in the FPGA device, are discussed and compared. Numerical results show that the OFDM scheme based on  (⋅)-II and (⋅)-III, which is a modified version of the hermitian symmetric (HS)-OFDM scheme, which performs both baseband and passband data communications, demands the lowest hardware resource utilization and power consumption, reducing to 1/3 the hardware resource utilization. As a result,  (⋅)-II and (⋅)-III constitute an interesting candidate for implementing new generations of high data rate, low hardware resource utilization, and low-power consumption clustered-OFDM-based transceivers for broadband data communication. Last but not least, numerical results show that the controllers used to integrate all components of a clustered-OFDM-based transceiver can demand sizeable hardware resource utilization and power consumption and, therefore, they have to be carefully designed.

This work presents the design of a 12 Mb/s Coded Orthogonal Frequency Division Multiplexing (COFDM) baseband processor for the standard IEEE 802.11a. The COFDM baseband processor was designed by using ourdesigned circuits for carrier phase correction, symbol timing synchronization, robust channel equalization and Viterbi decoding. These circuits are flexible, parameterized and described by using generic structural VHDL. The COFDM processor has two clock domains for reducing power consumption, it was synthesized on a Stratix II FPGA, and it was experimentally tested by using 2.4 GHz Radio Frequency (RF) circuitry.
