Abstract

La invencion se refiere a un aparato y metodo para procesamiento de datos particularmente util en la combinacion de convoluciones del codigo de dispersion, codigo mezclado y respuesta de canal con el fin de construir una matriz de coeficiente de transmision del sistema, mientras se mantiene el mismo tamano de circuito y tiempo de ejecucion relacionados al desempeno de cada convolucion separadamente. Un registro (200) para procesar valores de respuesta de canal reales y un segundo registro (100) para procesar valores de respuesta de canal imaginarios, se utilizan para mover respuestas de canal a traves de la convolucion. En lugar de multiplicadores, se utiliza un numero minimo optimizado de sumadores (A12-A1; A25-A28) conectados en una configuracion piramidal para efectuar la multiplicacion necesaria de los codigos, por simplicidad de construccion. Al concluir la transformacion de codigo de canal de la representacion binaria a representacion compleja como parte del metodo completo, se eliminan del aparato los sumadores innecesarios.
