Abstract:
1. A method for adjusting the gains of a radio receiver for packetized data, the radio receiver having one or more adjustable gains and including a first set of one or more analog-to-digital converters (ADCs) to convert one or more analog received signals to samples of the received signals, the method comprising: adjusting the gains to a default gain level; measuring the received signal strength (RSSI) over a relatively wide dynamic range; with the gains at the default gain level, detecting a start event by using the measured RSSI, the start event indicative of the radio receiving a packet; determining an estimate of the start of packet (SOP) time; using the received signal samples from the ADCs, obtaining a fine measure of the average signal strength; and adjusting the gains of the radio receiver to a fine gain level according the fine measure of the average signal strength, such that the receiver gains are set to receive the remainder of the packet indicated by the start event.
