Low data-rate communication is an effective approach for Internet of things (IoT) devices such as measurement nodes of wireless sensor networks which are required to operate at very low power. While a method which enables the receivers to perform the accurate carrier recovery for low-CNR and low-data-rate communication was proposed, the major difficulty has(More)
A spread spectrum technology is known to be able to expand the distance of wireless communications by improving the processing gain. However, the effective processing gain is decreased due to the phase shift between the two transceivers. We have studied the compensation algorithm of this phase shift, and its performance has been evaluated by a computer(More)
