Abstract
A novel distributed transversal filter technique for code division multiple access systems is proposed. It is observed that the distributed amplifier principle underlying the filter approach enables the generation of multi-gigahertz waveforms with suitable accuracy. The DTF method is considered in the context of phase-addressing code division multiplexing systems. Simulation results based on a full layout design illustrate the viability of the approach.
Keywords: Distributed transversal filter, code division multiple access, spread time coding, periodic correlation.
Resumen
En este artículo, se propone una técnica de filtro transversal distribuido para el diseño de sistemas de multicanalización por división de código (CDMA). Se muestra que el principio de amplificación distribuida, método en el que se basa el filtro transversal, permite la generación de formas de onda en el régimen de multi-gigahertz con una adecuada exactitud. El método es considerado en el contexto de sistemas de multicanalización con codificación y decodificación de fase. Resultados de simulación de un diseño completo a nivel de layout ilustra la viabilidad del método propuesto.
