Abstract:
1. An asynchronous receiver system comprising: a plurality of antennae; an asynchronous receiver circuit having a signal input, the asynchronous receiver circuit being configured to asynchronously receive a wireless signal at the signal input, the asynchronous receiver circuit being further configured to generate at least a first quality signal responsive to the received wireless signal; a switch configured to controllably select one of the plurality of antennae for coupling to the input of the asynchronous receiver circuit responsive to a control signal; a controller configured to receive the first quality signal and generate the switching control signal, where the controller is configured to sequentially select each one of the plurality of antennae, measure the first quality signal and start a timer with a time value for the selected antenna, select a next one of the plurality of antennae if the timer expires, store the measured values for the first quality signal, and select one of the plurality of antenna to receive a remainder of a data packet based on the measured first signal quality values for the plurality of antennae.
