Implementation Approaches Trade-Offs for WiMax OFDM Functions on Reconfigurable Platforms

Ahmad Sghaier, Shawki Areibi, Robert Dony
2010 ACM Transactions on Reconfigurable Technology and Systems  
This thesis investigates three approaches to implement the OFDM functions of the fixed-WiMAX standard on reconfigurable platforms.  ...  The custom RTL approach showed the ability of a medium size FPGA to accommodate the design with only 50% occupation rate. The AccelDSP approach showed an area overhead of 10%.  ...  The first challenge is channel fading, which is caused by the multi-path effect. In the multi-path effect, the signals traverse different paths to reach a receiver.  ...

Here we propose a solution based on the combination of a frequency comb source and a fibre spectrometer, exploiting all-fibre technology.  ...  Being based on all-fibre technology, our system is inherently low-cost, lightweight and may lead to the development of a new class of broadband high-resolution spectrometers.  ...  To reconstruct the original spectra, we adopted a matrix pseudo-inversion algorithm based on singular value decomposition.  ...
