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.
