Abstract
A collision handling receiver for use in a data communication network. The collision handling system and method comprises collision handling receivers together with transmitters inserting pseudo-random delays. Accordingly, multiple sources may transmit simultaneous messages to a receiver so that the messages arrive with varying signal levels and times of arrival. The receiver sorts the symbols into separate sequences by grouping together symbols having similar time of arrival. In addition, the receiver retains the sequences with sufficiently reliable symbol detection, for example, when 75% of the symbols in a sequence are detected with sufficient quality. Receiver then ranks the retained transmitters by received signal level and decodes the messages from transmitters with highest received signal level.
