Abstract
Official abstract text for this publication.
A communication device is disclosed. The device may be in particular a radio transmitter and a receiver that can operate with low power consumption and with improved interference rejection, therefore particularly suitable for use in low-power communication systems, such as wireless sensor networks and wireless body area networks. In one aspect, multiple frequency tones (carriers) are used to carry information from the transmitter, such that a RF signal having multiple radio frequency components is produced and transmitted. In the receiver, an envelope detector is still the RF down-converter. After down-converting intermodulation components are extracted containing amplitude, phase and frequency information of the multiple radio frequency components. This allows the desired signal (the baseband information) to be distinguished from the carriers and unwanted interference.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of rejecting interference in a communication system comprising a transmitter and a receiver, the method comprising: in the transmitter: up-converting a baseband signal to a radio signal by modulating the baseband signal with at least two frequency tones and producing the radio signal comprising at least two frequency signals; transmitting the radio signal; in the receiver: receiving the radio signal; filtering the radio signal by a f…
