Abstract

Pulsed OFDM (P-OFDM) is a proposed enhancement to Multi-Band Orthogonal Frequency Division Multiplexing which reduces the power and complexity of Ultra Wideband transceivers without sacrificing performance. In this paper, the effects of finite precision arithmetic in the mixed-radix Fast Fourier Transforms of P-OFDM architectures are analyzed using a noise model. The results of this analysis lead to the selection of optimal values for the wordlengths of the data and coefficients. Synthesis results based on these optimal wordlengths are presented for a Xilinx Virtex™-4 FPGA implementation.
