An apparatus and process for improving the performance of a cellular communication system using direct sequence spread spectrum techniques. The apparatus and process enable dynamic modification of communication system parameters including PN code length, chipping rate and modulation technique for transmission of a data packet. Modification is based on proximity of the transmitter and receiver, transmitter and receiver capabilities, and other factors. The system evaluates tradeoffs between data transmission speed and communication range to improve system performance.

Cette invention se rapporte à un appareil et à un procédé pour améliorer les performances d'un système de communication cellulaire utilisant des techniques d'étalement du spectre en séquence directe. Cet appareil et ce procédé permettent une modification dynamique des paramètres du système de communication, tels que la longueur de code PN, le débit des éléments et la technique de modulation pour la transmission d'un paquet de données. Cette modification se fonde sur la proximité de l'émetteur et du récepteur, sur les capacités de l'émetteur et du récepteur et sur d'autre facteurs. Ledit système évalue le compromis entre la vitesse de transmission des données et la portée de la communication, afin d'améliorer les performances du système.
