Abstract
In some wireless local area networks (WLANs), signals of different modulation types and rates can be received. To operate optimally, the gain of an amplifier in a receiver can be set based on a specific modulation type and rate. For example, the gain of a receive path amplifier can be changed based on one or more unique identifying characteristics in a received data packet. Once the unique identifying characteristics are located, they can be analyzed to determine which modulation type and rate are represented. The appropriate gain of the amplifier can be set based on the modulation type and rate. Advantageously, subsequent data symbols can be amplified with the set gain, thereby ensuring that the receiver optimally receives those data symbols.
