A DSP embedded system. Application to digital communication systems

In recent years, embedded systems based on microprocessors have progressed significantly. This fact allows to use powerful operating systems and programming languages with a high level of abstraction which facilitates the development of applications. This paper shows a communication system designed to be run on a BeagleBoard, a low-cost device based on the chip OMAP 3530. The developed system allows to manage audio signal and involves the wireless transmission of the signals between devices using the Bluetooth technology and a filtering step based on Wiener methodology that improve the signal-noise ratio. This work represents the starting point for implementing a set of signal processing applications on the BeagleBoard.
