Abstract
On this work a low cost OFDM transmitter for underwater sensor networks is presented. The transmitter is based on a low power microcontroller that governs a DDS in order to generate the output data -OFDM symbols- avoiding the IFFT computations. This solution represents a new design perspective for the current UWSN -mainly based on FPGAs or DSPs, allowing to reduce the cost, the power consumption and the size of the current transmitters.
