Abstract

Un système de communication produit un code orthogonal d'étalement continu pour un utilisateur, un signal d'utilisateur modulé en étalement utilise lesdits codes continus, puis le signal d'étalement est combiné par prémélange et transmis. Un récepteur traite ensuite le signal reçu en utilisant un filtre adapté à une voie.
