Resumo: | In communication services, the quality and integrity of the voice signal at the receiver is a relevant factor that telephone operators must consider. In this article, we study the impact of degradation that occurs in the transmission channel on the transmitted voice signal. Therefore, key parameters are used, such as the average opinion score (MOS) related to the voice signal and the bit error rate (BER), in order to qualitatively and quantitatively evaluate the speech signal in each scenario. A modulation simulation scenario is used, which considers the AWGN, Rician and Rayleigh fading channels, and two modulations: BPSK and QAM. These channels have different configuration parameters. Experimental results show that there are certain MOS quality index values for each type of channel with a specific configuration, showing that for each transmission scenario there is a need for adaptations in the modulation-channel-gain combination to obtain better performance. |

En este artículo estudiamos el impacto de la degradación que se produce en el canal de transmisión sobre la señal de voz transmitida. Por tanto, se utilizan parámetros clave, como la puntuación media de opinión (MOS) relacionada con la señal de voz y la tasa de error de bit (BER), para evaluar cualitativa y cuantitativamente la señal de voz en cada escenario. Se utiliza un escenario de simulación de modulación, que considera los canales de desvanecimiento AWGN, Rician y Rayleigh, y dos modulaciones: BPSK y QAM. Estos canales tienen diferentes parámetros de configuración. Los resultados experimentales muestran que existen ciertos valores de índice de calidad MOS para cada tipo de canal con una configuración específica, mostrando que para cada escenario de transmisión hay una necesidad de adaptaciones en la combinación modulación-canal-ganancia para obtener un mejor desempeño.Nos serviços de comunicação, a qualidade e integridade do sinal de voz no receptor é um fator relevante que as operadoras de telefonia devem considerar.
