Abstract

Un dispositivo (100) inalambrico de espectro disperso, puede incluir un receptor (110), un buscador (128), un controlador (130) de busqueda y otras caracteristicas. El controlador (130) de busqueda, genera selectivamente las senales de control para controlar el buscador (128), el cual busca una senal de espectro disperso. En una modalidad, la arquitectura del buscador (128) es configurable dinamicamente por el controlador (130) de busqueda para buscar selectivamente canales multiples usando bins de frecuencia multiple para la senal.
