Abstract :
The SDR devices along with GNU Radio Software tool have taken to a new level in designing radio communications systems. This technology uses blocks-processing software that substitutes everything that is far implemented at the physical layer hardware. By designing a software radio system, this paper presents the implementation of a real time voice Tx/Rx using an embedded GMSK modulation in USRP E110 devices, the system performance was evaluated from an cualitative and cuantitative viewpoint using Mean Opinion Score (MOS) and Modified Bark Spectral Distortion (MBSD) algorithm, another tests were also performed.
