- W3009968540 abstract "This paper represents to develop a new Radix Based FFT Algorithm for the analysis of Multiband OFDM and their FPGA parameters calculation, in order to reduce the complexity for the efficient operation of multiband -OFDM. This brief compares the use of multiplier less and DSP slice-based cross-correlation for IEEE 802.16d orthogonal frequency division multiplexing (OFDM) timing synchronization on Xilinx Virtex6 and Spartan-6 #64257eld programmable gate arrays (FPGAs). The natural approach, given the availability of embedded DSP blocks on these FPGAs, would be to implement standard multiplier-based cross-correlation. However, this can consume a signi#64257cant number of DSP blocks, which may not #64257t on low-power devices. Hence, we compare a DSP48E1 slice based design to four different quantization of multiplier less correlation in terms of resource utilization and power consumption. OFDM timing synchronization accuracy is evaluated for each system at different signal to-noise ratios. Results show that even relatively coarse multiplier less co-efficient quantization can yield accurate timing synchronization, and does so at high clock speeds. Multiplier less designs enjoy reduced power consumption over the DSP48E1 Slice-based design." @default.
