Multifunctional communication transceiver with distance measurement capability
2014
In this work, a multifunctional communicator with distance measurement capability is presented to offer a high performance solution for the emerging intelligent sensor network applications, such as the intelligent transportation systems. The proposed transceiver architecture is highly optimized for sensor unit with multiplexed Tx/Rx antenna. The hardware architecture of the multifunctional communicator is introduced and well validated by a transceiver prototype. Both high quality waveform generating for detection purpose and flexible digital modulation for wireless communication are realized. The transceiver has a phase noise performance of −126 dBc/Hz at 10 KHz offset and −147 dBc/Hz at 1 MHz offset with a central frequency of 1.75 GHz, being qualified for near range distance measurement.
