Abstract
A method is performed by an intermediate device in a wireless network. The method includes estimating a first hop channel state based on a transmission originating from a first device. The method further includes estimating an end-to-end signal-to-noise ratio base on a transmission associated with a second device. The method also includes adapting a filter or an amplifier of the intermediate device based on the first hop channel state and the end-to-end signal-to-noise ratio.
Claims27
A method performed by an intermediate device in a wireless network including a first hop between a first device and the intermediate device, and a second hop between the intermediate device and a second device, the method comprising:
- estimating a first hop channel state based on a transmission associated with the first device;
- estimating an end-to-end signal-to-noise ratio based on a transmission associated with the second device;
- and
- adapting a filter or an amplifier of the intermediate device based on the first hop channel state and the end-to-end signal-to-noise ratio.
An intermediate device in a wireless environment including a first hop between a first device and the intermediate device and a second hop between the intermediate device and a second device, the intermediate device comprising:
- one or more antennas;
- and
- a processing system configured to:
- estimate a first hop channel state based on a transmission from the first device;
- estimate an end-to-end signal-to-noise ratio or a second hop signal-to-noise ratio based on a transmission from the second device;
- and
- adapt a filter or an amplifier based on the first hop channel state and at least one of the end-to-end signal-to-noise ratio or the second hop signal-to-noise ratio.
A computer program including instructions stored on non-transient computer readable media which, when executed, perform the acts of:
- estimating a first hop channel state based on a received first hop transmission;
- estimating second hop signal-to-noise ratio or an end-to-end signal-to-noise ratio based on a received second hop transmission;
- and
- adapting at least one of a filter or an amplification parameter based on the first hop channel state and at least one of the second hop signal-to-noise ratio or the end-to-end signal-to-noise ratio.
