LOW POWER ULTRA WIDEBAND TRANSMITTER AND RECEIVER

摘要

low-power transmitter and / or receiver devices are at the expense of time and / or frequency diversity to reduce the power consumption is provided by. To indicate that the channel condition is not required for the time and / or frequency spreading this transmission, the transmitter may not enter the power conservation mode, wherein the transmission is performed using the time gating scheme or time repeat scheme. Time gating in the scheme, the symbols a plurality of times instead of only once, but being transmitted using the increased transmission power. Repeat scheme in time, copies of the same symbols, instead of being retransmitted on different frequencies in different symbol transmission period, a plurality of times and is transmitted on the same frequency in different symbol transmission periods. As a result, the symbol is generated once and can be stored for a subsequent re-transmission, the transmitter / receiver part of the chain components will be able to be operated at a lower duty cycle, or the processing speed to conserve power. ;
