ULTRA-WIDEBAND COMMUNICATION APPARATUS HAVING DYNAMIC FREQUENCY SCALING FUNCTION FOR LOW POWER MODE

摘要

PURPOSE: An ultra-wideband communication apparatus including a dynamic frequency scaling function for a low power mode is provided to prevent the performance of the apparatus from deteriorating by variously regulating a data transmitting sub-carrier. CONSTITUTION: A transmitting unit(100) converts data stream to be transmitted in a pre-set orthogonal frequency division multiplexing symbol. A dynamic frequency scaling unit(200) selects a power mode based on information from a required transmitting rate, a low power mode state, the remained amount of a battery. The dynamic frequency scaling unit changes the clock frequency of the transmitting unit based on the selected power mode.
