Abstract

Una realización ilustrativa toma la forma de un sistema para localizar transmisores inalámbricos empleando un esquema de modulación digital por Multiplexión por División de Frecuencia Ortogonal (OFDM). El esquema OFDM incluye transmitir componentes de señal por canales de frecuencia de banda estrecha que abarcan un canal de banda ancha. El sistema incluye un primer sistema receptor configurado para recibir una fracción de los componentes de señal transmitidos por un primer transmisor inalámbrico a localizar en una fracción de los canales de frecuencia de banda estrecha, y para procesar la fracción de los componentes de señal con el fin de derivar mediciones relacionadas con posición. El sistema incluye además al menos un segundo sistema receptor configurado para recibir la fracción de los componentes de señal transmitidos por el primer transmisor inalámbrico, y para procesar esta fracción de los componentes de señal con el fin de derivar mediciones relacionadas con posición. El sistema también incluye un sistema de procesado configurado para usar mediciones relacionadas con posición de los sistemas receptores primero y segundo para calcular la posición del transmisor inalámbrico.
