Abstract

In this paper, we present findings relating to frame synchronization algorithms for software radio based OFDM systems in addition to an overview of the design and implementation of an (OFDM) software radio based on a general-purpose processor (GPP) platform. The objectives of this work are to advance on existing research carried out in the area of reconfigurable wireless flexible architecture nodes, which are subject to multipath fading, Doppler effects, and adjacent channel interference and have low cost yet robust and reliable operation requirements. We also include findings dealing with bit error rate (BER) versus channel signal to noise ratio (SNR) for BPSK and QPSK modulation schemes, and also the effect of non real-time operating systems (OS) running on GPPs on the transmitter processing time.
