发明名称 Data compression over communications links which are exposed to occasional errors
摘要 Re-synchronization of sets of transmit and receive state variables in a communication system is achieved when an error is detected, without disrupting the connection. Each of first and second transceivers, connected by a communications channel, have a common set of transmit and receive state variables supporting a data encoding algorithm function. The transmitter of one of the first and second transceivers fist encodes data to be transmitted and updates the transmit state variables according to the data encoding algorithm and the receiver of the receiving transceiver validates whether or not each data block has been received correctly. During the process of decoding the data, the receive state variables are updated according to the same algorithm used to update the transmit state variables, thereby keeping the two sets of state variables in synchronism with each other. When an error is detected, re-synchronization occurs by switching to transparent mode in the direction of communication in which the error occurred and resetting the corresponding transmit and receive sets of state variables.
