ABSTRACT:
A communication system having a transmitter that supplies test sequences formed from several test frequencies and a receiver having test means for testing the quality of a channel. The test means calculates for the plurality of frequencies both the transfer function of the channel and the channel noise variance. By taking the noise caused by the receiver into account, the test means determine the most suitable frequency band and bit rate for the transmission. This information is supplied to the transmitter to establish the transmission.
