Abstract
Embodiments of a method and a device are disclosed. In an embodiment, a method for operating an ultra-wideband (UWB) device is disclosed. The method involves powering down a first receive path of a multipath UWB device while leaving a second receive path of the multipath UWB device powered up, powering down channel estimation, tracking, and demodulation functions of the second receive path, and performing an acquisition function using the second receive path while the first receive path is powered down and while the channel estimation, tracking, and demodulation functions of the second receive path are powered down.
Claims20
A method for operating an ultra-wideband (UWB) device, the method comprising:
- powering down a first receive path of a multipath UWB device while leaving a second receive path of the multipath UWB device powered up;
- powering down channel estimation, tracking, and demodulation functions of the second receive path;
- and
- performing an acquisition function using the second receive path while the first receive path is powered down and while the channel estimation, tracking, and demodulation functions of the second receive path are powered down.
A method for operating an ultra-wideband (UWB) device, the method comprising:
- powering down at least one receive path of a multipath UWB device while leaving only one receive path powered up;
- powering down channel estimation, tracking, and demodulation functions of the receive path that is powered up;
- and
- performing an acquisition function using the powered up receive path while all other receive paths are powered down and the channel estimation, tracking, and demodulation functions of the powered up receive path are powered down.
An ultra-wideband (UWB) device comprising:
- a first receive path configured to implement acquisition, channel estimation, tracking, and demodulation functions;
- a second receive path configured to implement acquisition, channel estimation, tracking, and demodulation functions;
- and
- a processor configured to:
- power down the first receive path while leaving the second receive path powered up during the acquisition function;
- and
- power down the channel estimation, tracking, and demodulation functions of the second receive path during the acquisition function.
