Abstract
When a plurality of transceivers share a common communication medium or radio frequency channel, then collision interference will result when two or more transceivers transmit simultaneously. In order to detect this simultaneous transmission, an interference detector apparatus compares the received information after demodulation to that of the transmitted information before modulation. The classification of the distorted signals into either of the two decoded output states permits this interference to be detected with a comparison. The output from the interference detector is used to interrupt the transmitter when collision interference is present on the medium. It is also used to inhibit the receiver from generating erroneous data during the interference duration.
