Antenna selection system and method
First Claim
1. A method of selecting an antenna to receive a data signal, the method comprising:
- transmitting a data signal to an antenna array, the antenna array including at least a first antenna and a second antenna, the data signal including a time period without data transmission;
estimating a first signal-to-noise ratio for the first antenna and a second signal-to-noise ratio for the second antenna during the time period without data transmission; and
selecting one of the first antenna and the second antenna based on a comparison between the first signal-to-noise ratio and the second signal-to-noise ratio.

Abstract
A system and method for wireless communication. The system can include a transmitter that transmits a data signal having a time period without data transmission. The system can also include a receiver including a first antenna, a second antenna, a switch that activates one of the first antenna and the second antenna, and a processor that estimates a first signal-to-noise ratio for the first antenna and a second signal-to-noise ratio for the second antenna during the time period without data transmission. The processor can control the switch to select one of the first antenna and the second antenna based on a comparison between the first signal-to-noise ratio and the second signal-to-noise ratio.

20. A communication system comprising:
-
a transmitter that transmits a data signal, the data signal having a time period without data transmission; and
a receiver that receives the data signal, the receiver including a first antenna, a second antenna, a switch that activates one of the first antenna and the second antenna, and a processor that estimates a first signal-to-noise ratio for the first antenna and a second signal-to-noise ratio for the second antenna during the time period without data transmission, the processor controlling the switch to select one of the first antenna and the second antenna based on a comparison between the first signal-to-noise ratio and the second signal-to-noise ratio. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A telemetry system for monitoring at least one ambulatory patient, the system comprising:
-
a transmitter that can be coupled to the at least one ambulatory patient, the transmitter transmitting a data signal including a time period without data transmission;
a receiver that receives the data signal, the receiver including a first antenna and a second antenna, a switch that activates one of the first antenna and the second antenna, and a processor that estimates a first signal-to-noise ratio and a first relative power for the first antenna and a second signal-to-noise ratio and a second relative power for the second antenna during the time period without data transmission, the processor controlling the switch to select one of the first antenna and the second antenna based on at least one of a first comparison between the first signal-to-noise ratio and the second signal-to-noise ratio and a second comparison between the first relative power and the second relative power. - View Dependent Claims (35, 36)
