Design of an OFDM Modulator Using IEEE 802. 11a for SDR
Abstract
This paper documents the design of a SDR Platform asa research tool. In order to keep costs to a minimum and provide the maximum flexibility a processor-less architecture is chosen. All signal processing is carried out using a standard notebook computer.The platform consists of hardware element base band transmitter (OFDM). Software defined radio perform itsprocessing through software (error correction, modulation, control over RF hardware…).The actual and next communication schemes tend to use OFDM systems in order to provide high baud rates and less inter-symbol interference. Fast converging methods to estimate the significant multipath components in fading wireless channels.
