Análisis del método matemático de detección SVD en cognitive radio
Resumen
En este trabajo, el desempeño del método de descomposición en valores singulares (SVD), aplicado a la detección de usuarios en una red móvil cognitiva es evaluado. El rendimiento del método SVD se analizó en términos de Probabilidad de detección (Pd) vs relación señal / ruido (SNR), obteniendo un modelo matemático basado en una distribución de probabilidad acumulada (CDF).
Los resultados se compararon con las CDF´s de los métodos SVD teórico y detección de energía, mediante el estimador estadístico de máxima verosimilitud (MLE), concluyendo que el método aplicado en el sistema evaluado superó a los métodos teóricos en términos de Pd.
