Abstract:
A transceiver comprising a transmitter and a receiver is a component of a user terminal. A transmitter-check signal is transmitted from the transceiver to a remote node. Errors in the transmitter-check signal are measured at the remote node. Transmitter-correction information based on the errors is determined within the remote node and sent back to the user terminal. The user terminal utilizes the transmitter-correction information to set a correction module in the terminal to counteract the errors within the transmitter.
