Low-power ultra-wideband transmitter and receiver

摘要

The receiver device and / or a low power transmitter is achieved by sacrificing a frequency diversity and time diversity / or in exchange for lower power consumption. Which indicates that channel conditions are not required for transmission frequency spreading and time spreading and / or transmitter enters the power saving mode transmission is performed using the methods repetition time or gating system time get. The gating system time, symbols only once instead of multiple times, and is transmitted at transmission power increased, however. The method repetition time, copies of the same symbol, instead of being re-transmitted on a frequency different symbol transmission periods different sent multiple times on the same frequency to the symbol transmission time period different. Therefore, it is possible to generate a single symbol, and stored for re-transmission of subsequent, whereby the processing speed or duty cycle lower than the number of transmitter / receiver chain components to save power it is possible that at to operate.
