摘要：A method and apparatus for providing spread spectrum communications. The apparatus starts with designated spread spectrum communications parameters, such as default transmitted power level, pseudo-noise (PN) sequence. PN sequence length, and frequency channel, having values which are chosen to ensure that spread spectrum communications can be carried out between a first station and a second station. The apparatus of the invention then changes the values of the spread spectrum communications parameters to the minimum values necessary to provide a given level of communications reliability. If the conditions facing the spread spectrum communication system change so that communications reliability falls below the given level, the apparatus resets the values of the spread spectrum communications parameters to the default levels and begins again to change their values to provide the given level of communications reliability. If the apparatus establishes that communications can reliably be carried out with narrowband communications techniques, the apparatus changes the parameters to provide narrowband communications at the minimum acceptable power level.
