RF RECEIVER ASK/FSK DUTY CYCLE OPTIMIZATION ALGORITHM

摘要

An RF receiver for receiving transmissions of different modulations includes cycling between a first mode for receiving transmissions of a first modulation that occurs frequently and a second mode for receiving transmission of a second modulation that occurs infrequently. The example RF receiver is cycled between a first modulation for receiving the FSK transmission from the TPM system and a second modulation for receiving the ASK transmission from the RKE system. The RF receiver cycles between different modulations to detect the most frequent FSK modulated transmissions while also detecting and receiving the relatively infrequent ASK modulated RKE transmissions without an undesirable delay.
