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 paper describes a device capable of performing the following tasks: it samples and decodes the composite video analog TV signal, it encodes the resulting RGB data into a MPEG-4 stream and sends it over a WiMAX link. On the other end of the link a similar device receives the WiMAX signal, in either TDD or FDD mode, decodes the MPEG data and displays it on the LCD display. The device can be a hand held device, such as a mobile phone or a PDA. The algorithms for the analog TV, WiMAX physical layer, WiMAX MAC and the MPEG encoder/decoder are executed entirely in software in real time, using the Sandbridge Technologies' low power SB3011 digital signal processor. The SB3011 multithreaded digital signal processor includes four DSP cores with eight threads each, and one ARM processor. The execution of the algorithms requires the entire four cores for the FDD mode. The WiMAX MAC is executed on the ARM processor.

We present a software-only implementation of an IEEE 802.11a (WiFi) receiver optimized for Intel multicore platforms. The receiver is about 50 times faster than a straightforward C implementation, i.e., an implementation that has the same functionality, but leaves optimization completely to the compiler. Our hand-optimized implementation achieves real-time for all data rates up to the maximum of 54 Mbit/s on a Core i7, clocked at 3.3 GHz, and for up to 12 Mbit/s on an Atom, clocked at 1.6 GHz, using two cores in both cases. To achieve this performance we use up to two threads, up to 16-way vectorization using Intel's SSE, and various other optimizations.
