ABSTRACT:
A method is disclosed for optimally adjusting the received bit detection threshold in a digital communication system, such as a TDMA system that is characterized by very short duration burst transmissions. In one embodiment of the invention, a half-duplex radio modem is used for transmission and receipt of messages for airborne and ground-based Automatic Dependent Surveillance-Broadcast (ADS-B) service. A feedback path is provided for in the transmission/receiver unit to provide the transmission signal to the receiver path. A bit detection threshold adjustment circuit receives the transmission signal. The circuit digitizes the analog baseband signal, detects the positive and negative peak values and calculates a peak-to-peak deviation value to define the bit detection threshold value.
