Abstract
<B>DISPOSITIVO E MéTODO DE ENTRELAçAMENTO E DESENTRELAçAMENTO PARA SISTEMA DE COMUNICAçãO<D> Um método para entrelaçar dados de entrada tendo um tamanho diferente de um múltiplo de 2^ m^ (m>1) é revelado. O método compreende o armazenamento seq³êncial de dados de entrada em uma memória; acrescentar um valor de deslocamento ao tamanho dos dados de entrada para fornecer um endereço virtual com tamanho 2^ m^ em que (m>1), e gerar endereços aleatórios nas áreas de geração de endereço e ler os dados de entrada da memória utilizando os endereços aleatórios gerados das áreas de geração de endereço.
