Abstract
UN APARATO DE ADAPTACION PARA RECIBIR UNA VIA EN PARTICULAR, QUE TIENE LA AMPLITUD MAS GRANDE, DE UNA SEÑAL DE ESPECTRO AMPLIO CON MULTIPLES VIAS. LA SEÑAL DE ESPECTRO AMPLIO ESTA MODULADA POR UN CODIGO DE MEMORIA. UN GENERADOR DE CODIGO DE MEMORIA (401) GENERA UNA SEÑAL DE CODIGO DE MEMORIA QUE TIENE EL MISMO CODIGO DE MEMORIA QUE LA SEÑAL DE ESPECTRO AMPLIO. UNA PLURALIDAD DE REGISTROS PARA DESPLAZAMIENTO DESPLAZAN LA SEÑAL DE CODIGO DE MEMORIA MEDIANTE UNA PLURALIDAD DE RETARDOS DE TIEMPO. EL PRIMER Y SEGUNDO CONTADOR DE ANILLO (405, 409) GENERAN LAS SEÑALES DE SECUENCIA PRIMERA Y SEGUNDA PARA CONTROLAR EL PRIMER Y SEGUNDO DISPOSITIVO DE CONMUTACION (407, 411). EL PRIMER DISPOSITIVO DE CONMUTACION CONMUTA SUCESIVAMENTE ENTRE UNA PLURALIDAD DE CONEXIONES DE LOS REGISTROS PARA DESPLAZAMIENTO EN UNA DIRECCION DE RETARDOS QUE AUMENTAN O DISMINUYEN PARA GENERAR LA SEÑAL DE CODIGO DE MEMORIA CON EL PRIMER RETARDO DE TIEMPO. EL SEGUNDO DISPOSITIVO DE CONMUTACION, CONMUTA SUCESIVAMENTE ENTRE LAPLURALIDAD DE CONEXIONES DE LOS REGISTROS PARA DESPLAZAMIENTO EN UNA DIRECCION DE RETARDOS QUE AUMENTAN O DISMINUYEN PARA GENERAR LA SEÑAL DE CODIGO DE MEMORIA CON UN SEGUNDO RETARDO DE TIEMPO. UN PRIMER CORRELACIONADOR CORRELACIONA LA SEÑAL DE ESPECTRO AMPLIA RECIBIDA EN LA ENTRADA CON LA SEÑAL DE CODIGO DE MEMORIA CON EL PRIMER RETARDO DE TIEMPO. UN SEGUNDO CORRELACIONADOR CORRELACIONA LA SEÑAL DE ESPECTRO AMPLIO RECIBIDA EN LA ENTRADA CON LA SEÑAL DE CODIGO DE MEMORIA CON EL SEGUNDO RETARDO DE TIEMPO. UN COMPARADOR GENERA LA PRIMERA Y SEGUNDA SEÑAL DEL COMPARADOR COMPARANDO LAS SALIDAS DEL PRIMER CORRELACIONADOR CON LAS DEL SEGUNDO CORRELACIONADOR.
