Cellular communication system with dynamically modified data transmission parameters

摘要

An apparatus and process for improving the performance of a cellular communication system using direct sequence spread spectrum technique (104) is disclosed. The apparatus and process enable dynamic modification of communication system parameters including PN code length, chipping rate and modulation technique (102) for transmission of a data packet. Modification is based on proximity of the transmitter (100) and receiver (150), noise level, transmitter and receiver capabilities and other factors. The system makes tradeoffs between data transmission speed and communication range to improve system performance.
