Patent ID: 7751785

Claim:
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.
