Abstract
This paper deals with the implementation issues of a digital transmitter for OFDM based WLAN systems. We explore different solutions for signal generation in baseband and in intermediate frequency taking into account the effect of the analog conversion in the overall performance. In order to minimize distortion of the cyclic prefix a new interpolation filter structure valid for OFDM signals is presented. Finally, the cost in area for FPGA implementation of every needed circuit is given.
