dc.description.abstractEl trabajo realizado expone el estudio de una multiplexación candidata para 5G teniendo como objetivo su implementación en una plataforma de radio definido por software (SDR). Se define la forma de onda Universal Filtered Multi-carrier (UFMC) como el objeto de estudio y se realizan simulaciones sobre su desempeño. Adicionalmente se proponen métodos para la implementación en un sistema real como sincronización y estimación de canal. Se elige una plataforma de desarrollo de SDR conocida como GNU Radio y se trabaja con la API y bloques existentes para construir un prototipo de transceptor. Finalmente se selecciona el hardware USRP para la puesta prueba del sistema con un canal real y se realizan mediciones experimentales iniciales en laboratorio para contrastar los resultados con la teoría. Se comprueba el desempeño espectral de UFMC de forma experimental y se perfila como una candidata sucesora a OFDM. Se logra establecer que aunque los efectos de offset de frecuencia y tiempo, y canal deben compensarse, el efecto no lineal del amplificador de la mano con el alto PAPR de la señal son los principales contribuyentes en el desempeño de la transmisión y de las curvas de BER vs Eb/N0.
dc.description.abstractThe present work reports the study of a candidate waveform for 5G, aiming at its implementation in a software-defined radio platform (SDR). The Universal Filtered Multi-carrier (UFMC) waveform is selected as the object of this study, alongside which some simulations are carried out to verify its performance. Additionally, we propose methods for implementation in a real system such as synchronization and channel estimation. The GNU Radio SDR platform is chosen for development in order to work with its API and signal processing blocks to build a transceiver prototype. Finally, the USRP hardware is selected to test the system with a real channel and initial experimental measurements are made in the laboratory to contrast the results with the theory. The spectral efficiency of UFMC is verified experimentally and is outlined as a successor candidate to OFDM. It was possible to establish that although the effects of offset of frequency and time, and channel must be compensated, the non-linear effect of the amplifier alongside with the high PAPR of the signal are the main contributors in the performance of the transmission and the curves of BER vs Eb / N0.
