We present findings relating to frame synchronization algorithms for software radio based OFDM systems and 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 low-power re configurable wireless flexible architecture nodes, which are subject to multi-path effects. We also include findings dealing with Bit Error Rate (BER) versus channel Signal to Noise Ratio (SNR) for m-aryPSK modulation schemes, in addition to the effects due to non real-time Operating Systems (OS) based radios.
