A method and systems to test a communication system (200) comprising a
plurality of emitters (205), receivers (210) and channels (220) are
disclosed. According to the method of the invention the data used for the
test are preprocessed so as to be analyzed on the fly by the receivers
during the test. In a preferred embodiment, a connection identifier value
characterizing emitter and receiver addresses as well as data properties,
if any, is associated to each data and CRC bits are computed to format
frames comprising data, connection identifier value and CRC bits (410).
During the test, the communication system transmits frames from emitters
to corresponding receivers. Upon frames reception, receivers extract data
(455), connection identifier value (460) and CRC bits (465) and compute
CRC bits on received data (470). The comparison (475) of transmitted and
computed CRC bits in receiver allows determining whether or not frames
have been well transmitted.
