Estimating the term…
The present invention is enclosed in the area of wireless communication systems, generally towards the problem of multipath interference, and specifically towards mitigating the effect of standing wave in indoor positioning systems. The present invention includes a standing wave cancellation wireless transmitter configured to, for each signal with wavelength λ to be transmitted, transmit a first wave with wavelength λ and a second wave with wavelength λ and a shift equal to half the wavelength λ. It is also part of present invention a standing wave cancellation wireless receiver configured to perform the average of a first wave with wavelength λ and a second wave with wavelength λ and a shift equal to half the wavelength λ, creating a single received signal and, a system comprising at least one of said wireless transmitters and at least one of said wireless receivers and a method implemented by the said transmitter and receiver.
Standing wave cancellation wireless transmitter (1) characterized in that it is configured to, for each signal with wavelength to be transmitted, transmit a first wave with wavelength λ and transmit a second wave with wavelength and a shift equal to half the wavelength λ.
Standing wave cancellation wireless receiver characterized in that it contains means to perform the average of a first wave with wavelength λ and a second wave with wavelength λ and a shift equal to half the wavelength λ, configured to create a single received signal.
