Abstract: In a communication receiver circuit, an amplifier circuit can include an adjustable gain. A signal corresponding to a portion of a transmitted frame can be received, and a gain of the receiver circuit can be adjusted such as automatically, and such adjustment can be referred to as automatic gain control (AGC). An offset correction can be performed to adjust for an error in a received representation of a transmitted carrier, and such offset correction can be referred to as carrier frequency offset (CFO) correction. A portion of the received signal can be dynamically allocated between AGC and CFO correction, such as allocating a longer duration to CFO correction when AGC results in a relatively higher receiver gain, and allocating a shorter duration to CFO correction when AGC results in a relatively lower receiver gain.

Abstract: Aspects of this disclosure relate to transmitting and/or receiving a frequency-shift keying signal including a packet that includes a preamble and a payload. The preamble has a first modulation index that has a smaller magnitude than a second modulation index of the payload. This can enhance frequency correction in a receive device that receives the packet.
