Adaptive system for self-tuning a receiver in an RF communication system

摘要: A system for adaptive self-tuning of a receiver in radio communication system. Prior to transmission each data package from transmitter receiver, the generates sequence predefined test bytes (test sequence) n times. An identical version is stored receiver. Circuitry provided selected states tuning impedances varying center operating frequency wherein are equal number sequences. microcontroller compares received with and creates table correlating respective error bits detected state. The then selects impedance state characterized by least bits, thereby selecting optimal central carrier generated transmitter.
