Abstract

A method is proposed and evaluated for energy-efficient adaptive transmission in direct-sequence spread-spectrum packet communications over specular multipath channels. The power, code rate, and symbol rate are adapted to match the multipath profile and propagation loss of the wireless communications channel. The adaptation of the transmission parameters is based on several statistics that can be derived in a spread-spectrum receiver. The transmission parameters are selected to optimize a performance measure that is related to the energy consumption and time duration of a packet transmission.
