摘要： A processor duplexing method is applied to a 3G mobile communication system switching operation without involving application software. In this method, Real-Time operating system (RTOS) detects that a duplexing operation is being performed. While the duplexing switching operation is being performed, the RTOS and a PCI controlling unit dump a memory of an active board to a standby board, thereby synchronizing a memory between the active board and the standby board. Once the duplexing switching operation is complete, the standby board sequentially starts operation of the active board. In this method, duplexing of a processor level is performed without using application software in the RTOS. Instead, duplexing is a performed by a substructure (hardware and OS). As a result the burden of having the application software grow larger and more complicated is significantly reduced.

摘要： Provided are a data transceiver and method for performing equalization and pre-emphasis adaptive to the transmission characteristic of a transmitting part. The transceiver measures the signal attenuation characteristic of a transmission line of a receiving part using an input data signal input via the transmission line of the receiving part, decodes the distorted waveform of the input data signal, distorts the waveform of an output data signal beforehand using the measured signal attenuation characteristic of the transmission line of the receiving part, and transmits the output data signal via a transmission line of a transmitting part. Thus, when the output data signal is transmitted via the transmission line of the transmitting part, the waveform of the signal remains optimized.
