ABSTRACT:
An asynchronous receiver system has multiple antennae and an asynchronous receiver circuit with a signal input. The asynchronous receiver circuit receives a wireless signal at the signal input and generates a first quality signal responsive to the received wireless signal. A switch selects one of the antennae for coupling to the input of the asynchronous receiver circuit responsive to a control signal. A controller receives the first quality signal and generates the switching control signal. The controller sequentially selects each one of the antennae, measures the first quality signal and starts a timer with a time value for the selected antenna. The controller selects a next one of the antennae if the measured first quality signal value is below a threshold value and the timer expires and receives a remainder of a data packet based on the measured first signal quality values for the plurality of antennae.
